Let be a random variable with CDF . The moment generating function (mgf) of (or ), denoted by , is provided this expectation exists for in some neighborhood of 0. That is, there is an such that for all in , exists. If the expectation does not exist in a neighborhood of 0, we say that the moment generating function does not exist. In other words, the moment-generating function of X is the expectation of the random variable .
