Good afternoon,

This might be a simple question but here is my problem:

I want to understand or see which groups my xtlogit regression chose. I mean initially my panel data had 191 number of groups which is countries. But when I run the xtlogit number of groups are decreasing to 67, so I need to know which ones are dropped and which ones are used in the regression.

Is there a way to see this? Otherwise I will not be able to explain which countries were used in the regression.

Thank you in advance.
