Christiaan, Arthur van Soest has a recent paper where they estimate a two-part zero-inflated panel Poisson model using a first part logit and a second part truncated Poisson. You can extract the code for conditional likelihood estimation of the second part truncated panel Poisson from their Appendix A: http://arno.uvt.nl/show.cgi?fid=115295 As he notes, it is straightforward, but there seem to be few applications in the literature.

So far, I am only aware of STATA implementations taking into account the panel structure (e.g. xtpoisson, xtpqml) or the censoring (e.g. tpoisson) but not the combination of both. > > Best, > > Christiaan > > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/statalist/faq > * http://www.ats.ucla.edu/stat/stata/ -- Tirthankar Chakravarty tchakravarty@ucsd.edu tirthankar.chakravarty@gmail.com * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
