poisson regression with endogeneity and instrumental variables

[ilikesas]

Hi,

Is it possible to do in SAS a Poisson regression with endogeneity and instrumental variables? Also, how is it possible to test which variable is endogenous?

Thank you

It is about Econometric question , post it at Forecasting Forum, also check PROC COUNTERREG.

Thanks,

I already did. But Rick_SAS also transferred this question to this forum, so now it is posted twice?
