Properties of moment generating function
WebSince the probability density function of the original TS-LBIG distribution cannot be written in a closed-form expression, its generalization form was further introduced. Important properties such as the moment-generating function and survival function cannot be provided. We offered a different approach to solving this problem. WebThe moment generating function does not exist for realξ 6= 0, but the characteristic function M(iξ) ise− ξ (1 + ξ +ξ2/3). BothM(iξ) andK(iξ) =− ξ + log(1 + ξ +ξ2/3) have Taylor expansions aboutξ= 0 up to order four only. The normal distributionN(µ,σ2) has …

WebRecall that the moment generating function: \(M_X(t)=E(e^{tX})\) uniquely defines the distribution of a random variable. That is, if you can show that the moment generating function of \(\bar{X}\) is the same as some known moment-generating function, then \(\bar{X}\)follows the same distribution.
