docs: Determines moments (probabilistic measure) of all degrees specified by {@link #momentDegrees}.
  Moments are characteristics of random variables (in this case relating to the inserted values)
  <ul>
  <li>2nd moment: variance</li>
  <li>3rd moment: skewness (Schiefe)</li>
  <li>4th moment: kurtosis (Woelbung)</li>
  <li>...</li>
  </ul>
