Probability generating function -


what mean: find discrete multivariate distributions have explicit formula joint probability generating function? please if understand question , give example or expression me!

i assuming know mgf is. so, looking @ question, have find mgfs of multiple variate distributions.

for example, lets take poisson distribution. 1. univariate 2. discrete , has mgf

https://en.wikipedia.org/wiki/poisson_distribution

mgf can calculated e(e^tx) distribution.
