Dear Stata Users,
I am trying to run xtpoisson command with two additional fixed effects, which are importer time and exporter time fixed effects (it and jt, respectively). I have with 85000 observations and for 11 years (originally 500K+ with 20 years). My panel is strongly balanced. I execute comand as below;
and, after some iterations, get an error message as:
Note: I am using Stata 13 MP 8 core 64 bit, with 4 core, 64 bit, 6 ram pc. I have set max_memory to infinity, maxiter to 16000.
Kind Regards,
Dias Rafaj

Code:
xtpoisson trade fta1 fta2 fta3 i.it i.jt, fe vce(r)
and, after some iterations, get an error message as:
Cannot compute an improvement -- discontinuous region encounteredDoes anyone knows why this happens? And what would be the solution to this problem?
