Splet17. mar. 2016 · So if you are given the negative binomial MGF, all you need to do to calculate E[X] is to take the derivative of the MGF, and evaluate it at t = 0. To get the variance, recall that Var[X] = E[X2] − E[X]2, so you would calculate the second derivative M ″ X(0) at t = 0 and subtract the square of the previous result. Share Cite Follow
