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. WebThe method of moments uses as many moments of the distribution as are necessary to obtain a solu- tion. Many of the mathematical models that we use are described by one or two parameters. Hence, one or two moments are sufficient for a solution. In an occasional problem, we may find that the third moment must be utilized.
