Hi,
I wish to impose linear constraints when estimating an ordered probit model.
The internal 'oprobit' command does not allow constraints to be imposed.
Neither can I find the option amongst the various panel versions of this
estimator (reoprob, gllamm etc).
I understand that an ordered probit model written using Stata's -ml-
commands will permit the use of linear constraints. My initial concern is
for use on x-s data but a panel estimator would also be useful. My knowledge
of
programming is limited and I wondered whether anyone in the Stata community
had already devised such a program?
Regards,
William
