Then the estimate is given by Now we introduce g ( x ) = 1 + x as a control variate with a known expected value \ mathbb \ left [ g \ left ( U \ right ) \ right ] = \ int_0 ^ 1 ( 1 + x ) \ , \ mathrm x = \ frac and combine the two into a new estimate Using n = 1500 realizations and an estimated optimal coefficient c ^ \ star \ approx 0.4773 we obtain the following results The variance was significantly reduced after using the control variates technique .
 None
