st: setting cross-group constraints using gologit2

[William Magee <magee@chass.utoronto.ca>]

Dear Statalist Members,

I am trying to set constraints on cutpoints in gologit2
(whether that is a good idea or not is also a question)

I did the following, and got the following error.


. constraint 101 [0]_b[_const] = -.4716279

. constraint 102 [1]_b[_const] = -1.378691

. constraint 103 [2]_b[_const]= -2.806735

.
.
end of do-file

. do "/tmp/SD00244.000000"

. gologit2 homestranx  workstranx age0 age0sq if female ==1, link 
(cloglog) cons(101-103) auto(.01)

Testing parallel lines assumption using the .01 level of significance...

Step  1:  Constraints for parallel lines imposed for workstranx (P  
Value = 0.9847)
name found where constraint number expected
constraint numbers and matrices may not be combined
r(7);
-------------
I did this because I assumed that the equations are numbered as follows
(from the above model, both men and women included) :

I would welcome comments on whether it is  ok to try to do this as  
well as how to do this (conatrain cutpoints across equations).  BTW  
-- I did check for gender-related heterogeneity  using oglm...

 thanks,
