You don't say what version of Stata you have, but if there are three
levels and you have v10, then you should probably be using
-xtmelogit- instead of -xtlogit-.

I have a three-level hierarchical dataset, and have run both xtlogit and
gllamm, with similar results apart from the condition number and group level
variance, and I do not know what these large numbers are telling me.
1. is gllamm the right tool to use? And if not, what should I do?
2. if yes, then should I worry about the condition number and variances? And
what could I do to improve on them?
