Poisson: http://www.mathhelpforum.com/math-he...tributiom.html
Negative binomial: http://www.mathhelpforum.com/math-he...need-help.html contains what you need to do the calculations.
Ive been trying to wrap my head around these questions for a few days now and i seem to be getting nowhere with it
If anyone would take the time to help it would be greatly appreciated.
Ive attached the pdf here because i thought it would be easiest.
P.S. On another note does anyone know where i can find step by step derivations of mean and variance of negative binomial and Poisson random variables?
Thanks again
