Dear Statalist,

I run both a logit (xtlogit) and a tobit (xttobit) model for my research. I want to control for individual fixed effects, but I struggle with how to do this. For the year fixed effects I use i.year, however when I use i.id all the individuals are omitted because they predict success/failure perfectly.
I have an unbalanced data set, with five years of data --> N=8500.
