Generating moment function
WebNote that the mgf of a random variable is a function of t. The main application of mgf's is to find the moments of a random variable, as the previous example demonstrated. There … WebA generating function is particularly helpful when the probabilities, as coefficients, lead to a power series which can be expressed in a simplified form. With many of the commonly-used distributions, the probabilities do indeed lead to simple generating functions. Often it is quite easy to determine the generating function by simple inspection.
