Dear Statalist,

I've run my regressions and now I would like to confirm my results on a panel of firms that appeared in the survey more than once. I collected permanent IDs of those firms and tried to run the firm fixed effect by the i.permid command. However, the r(134) error message pops up. I have 32,881 observations altogether in the dataset, not sure how many of them are repeated but it could possibly be far too many.

Any alternative to the i.permid command?

Thank you very much!
