Web1 sep. 2014 · The moment generating function (mgf) of the random variable X is defined as m_X(t) = E(exp^tX). It should be apparent that the mgf is connected with a distribution rather than a random variable. In other words, there is only one mgf for a distribution, not one mgf for each moment. The mean and other moments can be defined using the mgf. el sur jorge luis borges english translation https://glassbluemoon.com
