I am estimating a model using conditional logit/fixed-effects logit, but using the command -xtlogit, fe- because it reports (and saves in e()) information on the number and size of groups. But in a sample with some very large group sizes, the number of groups and the maximum size of group from -xtlogit, fe- is different than what I calculate directly. For example:

This is a bug in -xtlogit- that will be fixed in the next ado-file update. Groups with more than 32,740 observations are not being counted. The bug only affects the calculations regarding the number and size of groups; nothing else is impacted.
