Subject: st: Brant test
Dear Statalist:
I tried to test the parallel slopes assumption of ordered logit regression
using the brant command, and got an error message of "not all independent
variables can be retained in all binary logits, brant test cannot be
computed". Does anyone know what may be the reason? Thank you very much.
Best
Gao
