Hello all
I'm moving back and forth between stata and R at the moment - of course,
using R whenever possible :-)
I'm running conditional logits on some panel data and I get slightly
different results and different N in the two programs.
That's probably because you are using method="approximate" in R.
I understand why Stata is dropping the groups with all outcomes the same...
this is inevitable in a conditional logit, right?
Yes.
Is R doing the same?
Yes.
