What if the model is like following:
pr( xb+u<0)=pr(outcome=1)
pr(0<xb+u<cut2)=pro(outcome=2)
pr(cut2<xb+u<cu3)=Pr(outcome=3)
...etc
the -xb- here does not include "constant" term.
But, the 1st cut point(cut1)==0 here.
I am thinking to use a constrained ologit (or oprobit) model.
However, from the description of command, -constraint-, I can not find any
setup for constrains with ologit or oprobit.
Can anybody help me this?
thank you very much and have a nice day
Jitian
