WebThe derivation of the characteristic function is almost identical to the derivation of the moment generating function (just replace with in that proof). Comments made about the moment generating function, including those about the computation of the Confluent hypergeometric function, apply also to the characteristic function, which is identical ... Webmoment generating function: M X(t) = X1 n=0 E[Xn] n! tn: The moment generating function is thus just the exponential generating func-tion for the moments of X. In particular, M(n) X (0) = E[X n]: So far we’ve assumed that the moment generating function exists, i.e. the implied integral E[etX] actually converges for some t 6= 0. Later on (on
