This chapter looks at Probability Generating Functions (PGFs) for discrete random variables. PGFs are useful tools for dealing with sums and limits of random variables. For some stochastic processes, they also have a special role in telling us whether a process will ever reach a particular state.

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. WebAs always, the moment generating function is defined as the expected value of e t X.

WebThe ordinary generating function for set partition numbers depends on an artiﬁcial ordering of the set. For such problems involving sets another tool is more natural: the exponential generating function. 1.2 Two variable 1.2.1 Binomial coeﬃcients There is something awkward about having two generating functions for ¡ n k ¢. WebAs always, the moment generating function is defined as the expected value of e t X. In the case of a negative binomial random variable, the m.g.f. is then: M ( t) = E ( e t X) = ∑ x = r ∞ e t x ( x − 1 r − 1) ( 1 − p) x − r p r. Now, it's just a matter of massaging the summation in order to get a working formula.
