Dear listers,

after estimating fixed effect regressions for an outcome with a limited number of values with -xtreg- and -xtologit-, I'd ideally like to explore how robust results are to Probit instead of Logit or the Linear Probability Model.
I've noted that Stata's -xtoprobit- or -xtprobit- do not allow for the fixed effect option, and I'm not sure whether moving to random effects instead would make much sense or how I would sensibly interpret such results then.

Technically I can circumvent that constraint by just manually adding the respective set of fixed effects to the list of controls, as the number of fixed effects would still allow me to compute it given my computer and enough hours of patience (I take it that there is no faster option like -areg- for Probit either?).

However, I'm wondering whether doing so makes sense if the number of fixed effects is not too large, or whether results would be biased so that I should abstain from using (O)Probit whenever I also wish to use fixed effects?

Thanks so much,
PM
