| Subject | st: no observation error after using xtpqml |
| Date | Mon, 18 Jul 2011 13:17:06 -0700 (PDT) |
Hello, I am using quasi maximum likelihood fixed effect Poisson in my paper. Most of cases, I got the coefficients with robust standard error. However, in one of my specification, after using xtpqml, I got the coefficient estimates but while calculating the robust standard error, I got an error message saying no observation. Is there any way to fix it?
