Dear forum,
May I ask what it is that causes a Poisson model to not converge?
I have a panel dataset of US imports (#OfProducts) from 130 exporters over 48 years. I am using the code xtpoisson y x1 x2 i.year, fe robust
I did want to interact the i.year#i.exporter, but the results do not converge.
Further, I have a second panel which instead as 15 other importers as well as the 130 exporters over 48 years.
Here, the literature seems to interact i.importer#i.exporter, however my model will not converge!
Thank you so much in advance
Kind regards
Ray
