Moment Generating Function of Chi-Squared Distribution
WebHere, we will introduce and discuss moment production related (MGFs).Momentaneous generating functions are useful by several reasons, one in which is their application to … WebThe theory of multivariate normal distributions (see for example [1] or [4]) provides a natural framework for a proof, but in introductory courses it is not always advisable to present it in that way. Alternatives are to be found for example in [8], [9] and [10], where proofs are given relying on the theory of characteristic functions or moment generating functions.
