Hi Debarchana,

DG> I'm encountered some problem using SPSS 10.0 (windows) while conducting DG> poisson and negative binomial regression.

DG> I went from regression- nonlinear regression; in the dialog box there is a DG> part which asks for model specification. i couldn't figure it out that part. DG> do we type something or we can choose form the options given under function.

You can run Poisson regression with SPSS with GENLOG, but negative binomial regression is not possible

DG> there is also a part called fucntions, which has several options. DG> now my question is which fuction is going to be appropriate for a study DG> where the dependent variable is count and of very low probability. whether DG> it is CDF poisson/negative binomial or r.v. poisson/negative binomial.
