WebFeb 4, 2024 · Now I wish to find its moment generating function, I know that for something to satisfy the conditions of a mgf it must have some finite answer for ∫ − ∞ ∞ e t x f X ( x) d x. My issue is that when I evaluate this integral, it diverges. Should my bounds for integration be my bounds for x, or have I made some error in understanding? WebThe joint moment generating function (joint mgf) is a multivariate generalization of the moment generating function. Similarly to the univariate case, a joint mgf uniquely …

For a discrete random variable X with support on some set S, the expected value of X is given by the sum. E [ X] = ∑ x ∈ S x Pr [ X = x]. And the expected value of some function g of X is then. E [ g ( X)] = ∑ x ∈ S g ( x) Pr [ X = x]. In the case of a Poisson random variable, the support is S = { 0, 1, 2, …, }, the set of ...
