Hi Stata users,
I am trying to use REGOPROB with a balanced panel (no missing
observations) and I kept getting a message "no observations" as soon
as the iteration begins. So I am getting no output. I have six
exogenous variables and I am willing to let one with the npl option
(to relax the parallel assumption).
Does anyone know what might be happening?
Thanks a lot for any insight,
Cesar
