Dear Stata listers,
I need to estimate an IV version of a panel data count model with
fixed effects (a la Hall, Hausman & Griliches). I believe that the
right approach for this problem is to look at the derivative of the
likelihood function as providing a set of moment conditions, and to
proceed using GMM. Has anyone programmed something like this in Stata?
It is rather easy to do in TSP (a package that has a great GMM
estimation routine), but I have made a rather large do-file investment
for this project, and would appreciate doing everything in my package
of choice...
Regards,
Pierre
