Subject: st: oprobit omodel

> In my data, the outcome is an ordered categorical variable, e.g., mild,
moderate and severe pain. I used oprobit. However, output from ado file omodel
tells me that coefficients are not equal across categories. What should I do
next? Is there any procedure that can output two sets of beta?
