WebReview of mgf. Remember that the moment generating function (mgf) of a random variable is defined as provided that the expected value exists and is finite for all belonging to a closed interval , with . The mgf has the property that its derivatives at zero are equal to the moments of : The existence of the mgf guarantees that the moments (hence the … Web8 nov. 2013 · Today, I wanted to publish a post on generating functions, based on discussions I had with Jean-Francois while having our coffee after lunch a couple of times already.
