moment-generating function

Statistics

The moment-generating function of a random variable X involves a variable, usually denoted by t, and is defined to be the expected value of e^tX. It is usually denoted by M_X(t), or M(X, t). Expanding M_X(t) in powers of t gives $moment-generating function$ where μ_r′ is the rth moment of X about the origin. By virtue of the Maclaurin series, μ_r′ is the value, when t=0, of the rth derivative with respect to t of M_X(t). See also probability-generating function.
