Re: st: constraints
This is illegal syntax, you specify the equation when specifying the
constraint not when estimating the mvprobit model. Reread carefully
-help constraint- and you will see that you have to specify something
like this:
constraint 1 [eq1]north=1
constraint 2 etc.
mvprobit ..., constr(1-some number)
It is up to you to figure out what the correct names of the equations
are (probably not eq1). You can do that by estimating the unconstraint
model and type:
matrix list e(b)
