Dear Statalists,
I am running a random-effects logistic model by the command -xtlogit depvar indepvar i.i, re vce(robust)-, where i refers to individual country
But Stata only shows the following results without anything more. In my previous post, I got valuable comments from Maarten that countries i=266, 270, 384, 404, 686, 768 and 834 do not have any variation in dependent variable.
So i would like to ask if there is any method to add country dummy to my model. My database consists of 45 countries and totally 900 observations.
Thank you very much!
