Webb28 juni 2024 · Moment generating functions can be defined for both discrete and continuous random variables. For discrete random variables, the moment generating function is defined as: MX(t) = E[etx] = ∑ x etxP(X = x) and for the continuous random variables, the moment generating function is given by: ∫xetxfX(x)dx.
