How to determine the overall model fit for Neg Binomial and Poisson Models?

Hi All,

Can someone explain me how I can determine the overall model fit for a negative binomial and Poisson model?

(I'm not an expert with SAS enterprise guide, so please explain it simple :-) )

 

I want to know how much of the variance is determined by my estimated models (in order to check if it's a steadfast model)

Thanks in advance,

Regards,

Peter
