st: Testing NegBin versus Gamma-Poisson

["Naji Nassar (MIReS)" <naji.nassar@mires.fr>]

Hi all,

I have purchases quantites made per customer per occasion..
I'd like to test that
- quantities are Neg bin distributed over purchase occasion
against
- purchase rate is Gamma distributed over customers
- quantities are Poisson distributed (indicidual purchase rate)


Best Regards
Naji
