I'm wondering if you can help me... I've been searching the web and
libraries.
I am looking for the proof for the Moment Generating Function of the
Negative Binomial Distribution.
m(t) = {[pexp(t)]/[1-qexp(t)]}^r
as well as proof of the
E[X] = r/p
and
V[X] = r(1-p)/p^2
Would you know where I might find them????
Any help would be appreciate, I've been looking in book stores, surfing
the net for weeks, and rummaging through libraries until my fingers
bleed.
Thank you, a desperate student.
