Just a follow-up note on my last posting. I still have not had any
replies from the R-experts our there that use partial proportional odds
regression (and I have to hope that there are some of you!) but I do
think that I have figured out how to perform the unconstrained partial
proportional odds
R-experts:
I would like to explore the partial proportional odds models of Peterson
and Harrell (Applied Statistics 1990, 39(2): 205-217) for a dataset that
I am analyzing. I have not been able to locate a R package that
implements these models. Is anyone aware of existing R functions,
