Are random errors necessarily gaussian? Errors are very often Gaussian, but not always. Here are some physical systems where random fluctuations (or "errors" if you're in a context with the thing that's varying constitutes an error) are not Gaussian: The distribution of times between clicks in a photodetector exposed to light is an exponential distribution....

Physics models rarely hint at ontological level. Throwing dice can be modelled as deterministic process, using initial conditions and equations of motion. Or it can be modelled as stochastic process, using assumptions about probability. Both are appropriate in different contexts. There is no proof of "the real" model.

You're right; the Schrödinger's equation induces a unitary time evolution, and it is deterministic. Indeterminism in Quantum Mechanics is given by another "evolution" that the wavefunction may experience: wavefunction collapse. This is the source of indeterminism in Quantum Mechanics, and is a mechanism that is still not well understood at a fundamental ...

An alternative way to generate random numbers, that truly is quantum, and also quite easy: put a small radioactive source near a Geiger counter. Radioactive decay is a truly random event in the quantum sense, and is basically not subject to thermal noise at all. For maximum visual impact, replace the Geiger counter with a cloud chamber. That way you can ...

Throwing dice is just throwing dice. That's all. It's not stochastic, nor deterministic. It's just throwing dice. Now we model throwing dice as a process, and that's where the stochastic or deterministic side starts to play in. It is the process that is stochastic or deterministic, not the throwing of the dice. It's how we think about the throwing of ...

The surprising answer is that nothing triggers it. In quantum mechanics all we can talk about is the probabilities of various events happening: whether they actually happen in a given period is truly random. There is no secret mechanism which we could find which controls whether an event happens or not. Well, there are, really, three-and-a-half ...

The decay phenomenon is a purely quantum mechanical property. This problem is equivalent to a particle in a finite potential well, and a lower potential state that is available outside the well. Classically if the energy of the particle in the well is lower than the potential barrier - it will never get to the lower state. By quantum mechanics, the particle ...

As noted in the comments this is a much studied question. Einstein, Podolsky and Rosen wrote a paper on it, "Can Quantum-Mechanical Description of Reality Be Considered Complete?", published in Physical Review in 1935, and universally known today as the EPR paper. They considered a particular situation, and their paper raised the question of "hidden ...

The fact is that there are two kind of things: 1) the wave function and 2) the physical observables.

This is really a footnote to Chris' answer but it got a bit long for a comment. It sounds odd to claim that a particle has no position, but it's easier to understand if you appreciate that a particle is just an excitation in a quantum field. When Heisenberg was developing his ideas physicists still thought of particles as little billiard balls. With the ...

Speaking loosely, each individual atom has a desire to become stable, but that translates into a probability of decaying. This means, since there are billions and billions of atoms in a macroscopically significat chunk of material, that there are always going to be unlikely holdouts, and these holdouts are responsible for radiation that after the initial ...

In quantum mechanics, the solution of the equations (Schrodinger, Dirac...), called wave functions are deterministic, at each $\left(x,\,y,\,z,\,t\right)$ point, but the only prediction they give is a probability distribution, which depends on the boundary conditions of the problem. $Ψ$ is a complex valued function, and measurements are real numbers and this ...

Look up Diaconis's work on flipping coins. While it is technically deterministic, what happens is that extremely small changes in the initial conditions flip the outcome. The same would be true of dice. When you shake them in your hand and throw, small changes would give different outcomes. What makes it seem random is that we can't control our hands well ...

14

The reason is probably the central limit theorem: When you add lots of independent random variables, their sum will form a normal distribution, irrespective of their individual probability distributions. This makes normal distributions a pretty good guess if you do not have information about the origin of the error or if you have multiple sources of error. ...

Although the uncertainty principle stems from the mathematical structure of QM, i.e., originates from the noncommutivity of some observable letting them behave as fourier transform pair as explained in another answer, I still think it is a statement on measurements, (i.e., imposes fundamental limits on measurements) since QM itself seems to be a theory of ...

The easy answer is "no one knows". The Schrödinger equation is just an equation that old Erwin threw together that happened to fit the experimental data. It is not even consistent with relativity theory (second derivative of space but only first of time) so clearly something is wrong with it. It just happens to work real well for engineering.

I believe spontaneous means it happens on its own. You don't need any outside influence to get the isotope to decay. This term is sometimes used in contrast to stimulated. Random means one cannot know precisely when the next decay will happen, though one can predict the probability of such events occurring in some time interval. A decay process can be both ...

The magnet has a finite moment of inertia. What would happen when the magnet with "wrong" orientation enters Stern-Gerlach apparatus? Of course, the magnetic field will exert torque on it. The magnet starts rotating. After it comes to the equilibrium orientation, i.e. is oriented along the field, the torque is zero, but angular velocity is at maximum, and ...

If I understood correctly, what you are trying to build is a hardware based random number generator, where you want to use some quantum mechanics-based mechanism to supply the randomness. I'm no experimentalist, thus, take my comments with a grain of salt. Your suggestion is to use Schottky noise from a illuminated photodiode. I believe that it's a pretty ...

Answers here have generally addressed the different question of whether empirical variables should be Gaussian, but 21joanna12 asked about experimental errors, which admit a completely different analysis.

If you look at the actual equations governing quantum mechanics, there is no randomness at all. The nucleus starts out in a state where it hasn't decayed. Over time, it evolves into a mixture of the undecayed state and the decayed state. It's like Schrodinger's cat. Gradually the mixture shifts more and more toward decay. If an observer watches the nucleus ...

To add to Nathaniel's Answer because (1) it is a good answer and (2) I get nervous recommending radioactive materials handling to anybody I don't know: I would really think about the cloud chamber idea, especially since you're a software guy with a math background.

In the standard interpretation of quantum mechanics the time-evolution of the system and what we observe are separated (unlike Newtonian mechanics). The system, while unobserved exists in a superposition of states (all the states that satisfy the Schrödinger equation). These states (while unobserved) evolve in time according to the Schrödinger equation. This ...

The experimental result that the rate of decay is measured to be proportional to the amount of undecayed particles actually confirms memorylessness. This is because this result, together with the assumptions that the particles are not "communicating" with one another and that they are identical confirms that the probability density of the time to decay for ...

Understanding the uncertainty principle really only involves accepting the idea that, at small scales, elementary particles behave like waves.

# Understanding Financial Risk: A Deep Dive

February 09, 2018

Investment in the stock market is not always an easy journey. It is risky by nature. Markets are largely unpredictable even to senior analysts and can make a turn at any moment in the opposite direction. Many analysts describe the markets as random. Because of this randomness, there is no single investment strategy that works every time. However, different strategies can expose you to different levels of risk.

# What is Risk?

Risk is the probability that an adverse event happens (implying negative impact). Two key elements are particularly important in this definition.

First, the probability — adverse events may or may not occur.

Second, impact — the adverse event has a negative impact, mostly in terms of financial losses in the stock market.

Usually, those two elements (probability and impact) define how severe the risk is. This risk is quantified in a measure known as a risk score. This score is calculated by multiplying the mathematical probability of the risk by the negative impact. Investors should give more attention to risks with higher scores since they are more serious.

Typically, an adverse event affects the value of your investment negatively. Investors often have financial goals to achieve, and any event that can affect their ability to achieve those goals is usually considered a risk.

# Most Common Types of Risks

## Market Risk

The value of your investment may fluctuate based on the price’s movement up and down. Typically, this risk is associated with equities since their value can fluctuate. For example, if the investor bought a share of Amazon at $100, expecting its price to go up. The market risk here is that the price declines significantly to below$70 for example. Fixed income securities are not affected by this risk unless the investor wants to sell his bonds, since the interest rate on fixed income assets will remain the same regardless of the price of the bond.

Fixed income securities are debt instruments on which the investor earns a fixed interest rate on his investment at regular intervals

## Inflation Risk

The monetary value of your investments may fluctuate based on the level of inflation.

Inflations is a case of depreciation in the value of the currency. Deflation, on the other hand, is the case of appreciation in the value of the currency.

The risk of inflation is relevant when the investor is holding cash money (she has not invested yet), which means he has lost purchasing power due to inflation. For this reason, holding cash is not necessarily a risk-free activity. The risk of inflation also has an effect on the value of debt. Typically, inflation is negative for the lender since he will receive less purchasing power when his loan is repaid. For example, if you can purchase as asset for $100 today but after one year you require$120 to purchase it, then this is case where the money lost a part of its purchasing power.

## Systemic Risk

This is a major risk that can affect the entire financial system rather than a single asset alone. The most famous example is the financial crisis in 2008. This crisis was followed by the great recession as well as a credit crisis. Previous accounts of such crises were more severe, such as the great depression of 1929. This type of risk is major enough to warrant a government intervention to control damages and restore economic growth.

## Interest Rate Risk

This applies also to cash holdings such as deposits in banks. Deposit interest rates fluctuate based on economic conditions. If the economy is in a state of recession then the government will lower interest rate to encourage investment in the economy, whereas if the economy is experiencing high growth, the government may increase interest rates to put a limit on inflation and manage growth.

This has implications on how much you can earn on your deposits in the bank. It also applies to bonds since the interest rate can also fluctuate based on economic and geopolitical conditions. Example: you have a deposit in the amount of 50,000 USD in the bank, at an interest rate of 2%, but then the interest rate declines to 1% which reduces your earnings.

## Reinvestment Risk

This is the risk that the investor won’t be able to receive the same returns on the same amount in case he reinvests this amount at a later date. For example, if an investor buys a bond for $2000 at an interest rate of 5%, and at maturity date he receives back his$2000 plus interest payments, but at that time the interest rate is at 4%, and thus the investor will receive less earnings for the same amount if she was to reinvest again.

## Sovereign Risk

This is the risk that a government will not be able to pay its obligations such as debt in due time. This risk also includes the risk that a central bank will change their regulations regarding foreign exchange affecting the value of its currency.

For example, when the Swiss National Bank unpegged the exchange rate between the franc and the euro, the value of the euro dramatically decreased against the Swiss Franc.

# Analyzing Risk by Using Standard Deviation and Beta

## Standard Deviation

The standard deviation is one of the most popular measures of risk. It measures how much the price can deviate from its average. In other words, it measures the volatility of the price movement. Volatility makes prediction much harder, and therefore it might lead to losses due to poor reading or understanding of the market.

The standard deviation measures deviation from a central measure, and thus the higher its reading the more volatile the market is. Investors may seek to implement a mean reversion strategy when the standard deviation is too high. However, this strategy is not always safe to use as typically trending markets are characterized by long periods of price staying above average.

The mean reversion strategy is a strategy where investors assume that overstretched movements in the markets (long upward or downward trends) will be reversed, and that the price will eventually return to its mean value.

In the below graph the number in the center (μ) is the average whereas the σ symbol refers to the standard deviation.

2σ implies that the value is 2 standard deviations away, so μ-2σ implies that the value is 2 standard deviations below the mean.

The vertical axis is the data values. There are more data points as we come closer to the average in the normal distribution.

Standard deviation (X-axis)

## Beta

Beta is another measure of the volatility of the market. However, it measures a stock’s volatility in comparison with that of the market. In simple terms, Beta tells the investors whether a certain stock is historically less or more volatile in its movements than the overall market, helping the investor decide whether this is the right level of volatility for him. Beta is usually calculated by using regression analysis.

Regression analysis is the analysis of the relationship between one dependent variable and other independent variable(s) to discover the true nature of the relationship between those variables.

Beta is usually either higher or lower than 1. If the Beta for a stock is 1.5, then its volatility is higher than that of the market by 50%. If the Beta is 0.2, then the stock is five times less volatile than the overall market. If Beta is 1, then the volatility of the stock and the volatility of the market is the same.

Typically, investing in stocks with higher Beta means exposure to higher risk but also the possibility of higher returns as well. On the other hand, investing in stocks with low Beta is suitable for more conservative investors.

For example, Amazon stock has a beta of 1.75, therefore it is 75% more volatile than the overall market.

# Evaluating $\int_1^\infty \sin \frac{1}{x^2} dx$

Evaluating $$\int_1^\infty \sin \frac{1}{x^2} dx$$

Actually I'm quite curious whether we can have a good evaluation of this integral, because I found this equivalent to evaluate $$\int_0^1\cos(x^2) dx$$

My Attempt

\begin{align} \int_1^\infty \sin \frac{1}{x^2} dx &= \frac{1}{2} \int_0^1 \frac{\sin u}{ u^{ \frac{3}{2} } }du \\ &= -\int_0^1 \sin u\, d\frac{1}{\sqrt u} \\ &= -\sin 1 + \int_0^1 \frac{\cos u}{\sqrt u} du \\ &= -\sin 1 + 2\int_0^1\cos(x^2) dx \end{align}

But I got stuck on how to evaluate the integral mentioned above.

After a brief search I found that $$\int \cos(x^2) dx$$ doesn't have a closed form.

So can we evaluate this well? I would highly appreciate it if you could share any thoughts. Thanks in advance!

• wolframalpha.com/input/… – Michael May 21 '19 at 0:00
• @Michael Thanks, but I think the Fresnel C integral is not an elementary function. Is it possible to turn it into a form such as $\frac{\sqrt \pi}{2}$? – Zero May 21 '19 at 0:03
• Yes: Multiply the integral by 0 and then add $\frac{\sqrt{\pi}}{2}$. – Michael May 21 '19 at 3:14
• @Michael Are we seriously going to do that? Or Was that sarcasm? – Soumalya Pramanik May 21 '19 at 4:07
• @SoumalyaPramanik :both. – Michael May 21 '19 at 14:23

For an integral such as this, without looking up the relevant special functions, we can always just use the series:

$$\int_0^1\cos(x^2) dx=\sum_{n=0}^\infty \frac{(-1)^n}{(2n)!} \int_0^1 x^{4n} dx=\sum_{n=0}^\infty \frac{(-1)^n}{(2n)! (4n+1)}$$

This series converges fast and it's quite easy to get the numerical value to any precision.

But, as per Michael's comment, Fresnel integrals are the way to go. They are incorporated in modern software, such as Matlab or Mathematica, so evaluating them is faster than numerically evaluating the original integral.

# What is a linear transformation in plain english?

Every definition I find on Google utilizes vector spaces and mapping which are mathematical. If you have to use vector spaces and mapping please explain the mathematics behind it. Thanks.

A linear transformation is a function that behaves like functions that give us lines through the origin when graphed on the Cartesian plane. In particular, those functions are all of the form f(x) = ax for some constant a.
It is easy to see that incrementing x by h increments the function by the same function of h (ie., it is like tacking on a copy of "the line from f(0) to f(h)" to x by moving the origin to x). Mathematically, this says f(x + h) = f(x) + f(h): the function distributes over addition as if it were multiplication.
Also like multiplication, the function can be factored out of a product: f(bx) = bf(x).
These two properties define a linear transformation, no matter how abstract the field of study is. It is just a very simple type of function that behaves very nicely with respect to addition and multiplication of the elements in its domain and image. From the properties above, it is easy to see that these functions have their own internal algebra.
We generalize this by noting that x need not be just a number, but can be any object for which it is reasonable to define addition and scaling by a number. This leads to linear algebra and other algebras.
In physical terms in one dimension, when you change something by a particular amount in the domain, the related image is changed by a constant directly proportional amount. Ie., this is similar to changing the unit of measurement from inches to centimeters or vice versa. It does not matter what the particular value of inches is, only the change in inches that determines the change in centimeters. A nonlinear transformation would not be able to do this; one would have to specify the start and endpoint of the inches measurement in order to translate correctly, ie., if I(x) = x2. It is not true that I(x + h) = I(x) + I(h).
In more than one dimensional, a linear transformation can do more interesting things, such as rotation and shearing, where each dimension scales at a different rate than the others.
Another common generalization is generalizing all lines: f(x) = ax + b. These types of transformations are referred to as affine.

In fact, if f and g are linear, then f(g(x)) = g(f(x)), so we may as well write fg(x) = gf(x).

How would you word this equation? Is it f times g(x) is equal to g times f(x)?

These two properties define a linear transformation, no matter how abstract the field of study is.

Just to be clear slider, are you referring to multiplication and addition as the two properties of the functions that define linear transformation? What other choices do we have that makes a function "non-linear"?

In plain English a linear transformation is a way of stretching or rotating a map in such a way that strait lines remain strait after the transformation.

Can anyone explain what a domain and image is? Their differences? In simple terms. Then maybe throw in a mathematical example.

The domain of a function is just the set of all input values for which the function is defined.

The image of a function is the set of all possible output values from a function.

For example, if we are talking about real numbers

For the function f(x) = sqrt(x-1),
the domain is all numbers >= 1 (because you can't take the square root of a negative umber)
The image is all numbers >= 0 (because zero or any positive number is the square root of some number)

The reason linear transformations are defined in terms of vector spaces is because a "vector space" is the simplest mathematical structure for which they CAN be defined.

If you don't know what a vector space is, just think about a specific example of a vector space, for example the points on a plane, or in 3-D space, in "ordinary" (Euclidean) geometry.

A function is just some rule that takes a point and produces another point.

If you apply a function to all the points that make up a "picture" on the plane, you will transform it into another picture. Usuall this will "distort" the picture in some way, and in particular straight lines will finish up curved.

A linear transformation is one where every possible straight line in the original picture is transformed into another straight line (i.e. never into a curved line).

There are several simple linear transformations, for example
* Sliding (translating) the whole picture left and right, or up and down
* Enlarging or reducing the picture, either by the same amount in all directions or just in one direction (e.g. horizontally but not vertically)
* Rotating the picture by any angle around any point.
* "Shear transformations" that change rectangles into a parallelograms, or in other words they can change the size of the angles between lines in the picture, but the lines themselves remain straight.

It follows from the definition of a linear transformation that the result of any sequence of linear transformations applied one after another is equivalent to just one (more complicated) linear transformation.

In fact this idea can be more useful if you work it backwards, and demonstrate that any complicated linear transformation can be broken down into a sequense of "simple" transformations like the ones I described above. This is the basic idea behind a lot of the math used to generate computer graphics.

The domain of a function, f, is the set of all possible inputs to that function.

The image of a function, also called the range, is the set of all its outputs. The outputs are usually called the values of the function.

The image of a subset, S, of the domain is the set of all of the function's outputs, f(x), such that x is in S.

The codomain of a function is a set specified in the definition of the function which must contain all of its outputs, although it may contain other elements that aren't outputs of the function. The range is a subset of the codomain.

Notation. Let x be an element of the set D, the domain of the function f. Then f(x) is the value of f on x, and is an element of the range of f. The range of f may be denoted f(D). Let S be a subset of D. Then the image of S "under" f is f(S), a subset of the range.

For example, let f be a function from the set {1,2,3,4} (the domain) to the set {%,@,56,12,*,#} (the codomain) such that f(1) = *, f(2) = @, f(3) = @, f(4) = %. Then the image of the subset {1,2} is {*,@}. So is the image of the subset {1,2,3}. The image of the function (equivalently, the range of the function), i.e. the image of the whole domain, is {3,@,%}.

For example, let g be a function from the real numbers to the real numbers, R, such that g(x) = 2x. The domain is R. The range is R. The image of the interval (0,1), that is all real numbers strictly between 0 and 1, is the interval (0,2).

Just to be clear slider, are you referring to multiplication and addition as the two properties of the functions that define linear transformation? What other choices do we have that makes a function "non-linear"?

No, rather linear transformations distribute over sums and scalings, similar to the way multiplication by a constant distributes over addition and scaling. That is, the linear transformation of a sum is the same as the sum of the linear transformation applied to each term, and furthermore, the linear transformation of a scaled object is the same as the scalar applied to the transformation of the unscaled object. You will find this type of transformation in other guises as you study more mathematics.
They are quite neat. For example, suppose you know that L(5) = 3 and L is a linear transformation. You then know every value of L(x) for every x! For example, L(1) = L((1/5)*5) = (1/5)L(5) = 3/5.
For n dimensions, you will need to know n independent input-output pairs in order to know every value of the transformation. We need them to be independent because, for example, it is of no use to know two output values if the input values are multiples of each other, as that gives no new information, as seen if you worked the example above. The general argument brings us to linear independence, which brings about the usefulness of basis vectors and matrices.
For example, in two dimensions, you may be operating on ordered pairs of numbers that have addition and scalar multiplication defined. This is called a vector space. If v and w are elements in this space, called vectors, and r is a real number, called a scalar because we only use numbers to scale our vectors, then we can now mean something by L(v + w) = L(v) + L(w) and L(rw) = rL(w).
Ie., suppose we have L(1, 1) = (-1, 1) and L(1, -1) = (1, 1). We can now find the result of applying this transformation to any 2-dimensional vector.
You will study these concepts in detail in a course on linear algebra.
A related concept is that of an affine transformation. A very common 1-dimensional affine transformation (at least here in the U.S.A.) is the affine transformation between degrees Celsius and degrees Fahrenheit. Knowing that it is affine, and knowing two specific points, that 0 degrees Celsius is 32 degrees Fahrenheit (freezing point of water at STP) and 100 degrees Celsius is 212 degrees Fahrenheit (boiling point of water at STP) allows us to easily derive the full relationship for any particular temperature.

I would ignore this aspect until you have studied linear algebra further.

Every definition I find on Google utilizes vector spaces and mapping which are mathematical. If you have to use vector spaces and mapping please explain the mathematics behind it. Thanks.

Map and mapping mean the same as function: a pair of sets, called the domain and codomain of the function, and a rule associating each element of the domain (input) with no more than one element of the codomain (output) each.

A vector space is any mathematical structure which obeys the http://cnx.org/content/m10419/latest/ [Broken].

Transformation also means function, but the word is typically applied to a function whose inputs and outputs are vectors, or points of an affine space, as the case may be.

A translation is *not* a linear transformation; it is an affine transformation.

I am well aware of this which is why I posted the question.

Coco, you asked for a plain English explanation, rather than the mathematical discussion presented so far.

Well here goes.

A linear transformation is a formal mathematical way of presenting the idea of proportionality or the english "is proportional to".

For example

If I can shovel 1/2 a ton of sand in 1 hour I can expect to shovel 1 ton in 2 hours. That is proportionality.

The transformation is linear.

But consider my electricity bill

If I pay $100 for 100 units of electricity can I expect to pay$200 for 200 units?

Well, where I live at least, the answer is no because some of that first $100 is standing charge, which is the same, no matter how much electricity I use. So I actually pay$50 standing charge and 50c per unit so I pay \$150 for 200 units.

That is a non linear transformation.

All the rest is just fancy names for this.

In fact, if f and g are linear, then f(g(x)) = g(f(x)), so we may as well write fg(x) = gf(x).

Possible interpretation: composition of linear functions is commutative. Counter example: rotations in R3. So I guess it's not that... Could you disambiguate?

Possible interpretation: composition of linear functions is commutative. Counter example: rotations in R3. So I guess it's not that... Could you disambiguate?

Indeed, I'm going to remove that statement; it only holds in 1 dimension and specal cases and is not very enlightening.
