Hi All, I am trying to build a model with an ordinal dv (scale 1 to 4). We are looking for something like the adjacent category model that is available in proc catmod. However our independent variables are ratings on a scale of 1 to 10 and we have upto 25 of these. So proc catmod is ruled out.

One key goal is to have unique parameter estimates for each transition unlike a proportional odds model.

I believe we can do it in proc genmod by specifying a customized link using "fwdlink", "invlink", "deviance", and "variance" statements as such a link is not available inherently in proc genmod.

Any suggestions on how to fit such a model using proc genmod or any other sas procedure would be greatly appreciated.

Thanks, Zai
