Sebastian,

Here is a link to a post which I made previously about how to
fit a zinb model in SAS.

http://listserv.uga.edu/cgi-bin/wa?A2=ind0304B&L=sas-l&P=R29142

Modify the terms eta_zip and eta_nb to suit your model.  These
two linear combinations model the zero-inflation component and
the negative binomial expectation, respectively.

Dale
