The reason could be the sample itself, try
xtlogit, fe
xtlogit if e(sample), re
Or the quadrature, try
xtlogit, re quad(8)
R.

Subject: st: random effect logit model
Dear Stata Listers,
I am using STATA/SE 9.2 and running a simple random
effect logit model with a combination of discrete and
continuous independent variables. The dependent and
discrete independent variables are all dichotomous.
When I run it, after several iterations it says "not
concave" and keeps iterate with no results. Can
anybody provide any suggestions to make it work.
Thanks.
Pallab
