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.
