I attempted to modify Joseph Hilbe's 0-truncated negative binomial routine
(nbinlf.ado likelihood function) to accomodate for endogenous stratification
(e.g. on-site sampling), however I am running into problems during the
maximization process; probably inherent in the trnbin0.ado file which performs
the estimation.  Has anyone else attempted to do this?  Would anyone be able to
help?

Cheers,
Craig Meisner
