WebNov 8, 2024 · Moment Generating Functions. To see how this comes about, we introduce a new variable t, and define a function g(t) as follows: g(t) = E(etX) = ∞ ∑ k = 0μktk k! = E( ∞ ∑ k = 0Xktk k!) = ∞ ∑ j = 1etxjp(xj) . We call g(t) the for X, and think of it as a convenient bookkeeping device for describing the moments of X.
