Some output would be helpful. But if you are running xtlogit, why
would you want to exclude all outcomes that are 1 or 0? If there are
no 0s, then xtlogit (like logit) will fail.

Dear all

I want to run an xtlogit with fixed effects but Stata won't do it. It
complains about multiple positive outcomes within groups. I did exclude
observations where all outcomes are 1 or 0. It then reports a sorting
error. Why?
