PDF Lecture 6 Moment-generating functions - University of Texas at Austin Using MGF, it is possible to find moments by taking derivatives rather than doing integrals! MGF encodes all the moments of a random variable into a single function from which they can be extracted again later. In my math textbooks, they always told me to find the moment generating functions of Binomial(n, p), Poisson(), Exponential(), Normal(0, 1), etc. However, they never really showed me why MGFs are going to be useful in such a way that they spark joy. Answer (1 of 2): The moment generating function (MGF) of a random variable X, about the point 0, is defined as below; M(t, X) = M(t) = E(e^(tx)) = E(1 + tx . Take a derivative of MGF n times and plug t = 0 in. Proposition Let and be two random variables. Please consider the following alkane.
