Generalized ordered logit

[Demographer]

Hello,

I would like to know if it is possible with SAS to do a generalized ordered logit (different parameters for each response categories, such as in a multinomial logit).

With stata, I think it is gologit2, but I didn't find the equivalent function with SAS.

Thanks.

Proc logistic + unequalslopes can't do glogit ?

I'm not sure why, but when I add this option, it says : "The UNEQUALSLOPES option is ignored."

And the output is the same as a normal glogit. How should I use it?

proc logistic data=edu.educationClean;
class cohort4(ref='2') cntr_regr(ref=first)  /param=ref;
model edu3(descending)= cntr_regr cohort4 cntr_regr*cohort4 /link=glogit UNEQUALSLOPES=edu3;
run;

If you want an ordered logit, as you said, then you don't want the LINK=GLOGIT option.  Remove it to get an ordinal logit model.  See this note for examples.
