[R] Multilevel analysis for ordinal responses

[Duncan Mackay]

Hi

The package VGAM checks the assumption by the argument "parallel" and
comparing the 2 models with and without. 
I am not sure if package rms does so as well

Below  are some other packages that do ordinal regression, some have
marginal capability 
ordinal
repolr
multgee
geepack
nnet

I am not sure what is available in those to compare the parallel assumption

Subject: [R] Multilevel analysis for ordinal responses

Dear all,

I need to fit a multielvel model for an ordinal response. Does R have a
command for conducting a multilevel ordinal logistic regression when the
model violates the parallel regression or proportional odds assumption?
Additionally, are there any tests to check the parallel regression
assumption for the multilevel ordered model? Providing an syntax would be
really helpful.

Thanks in advance,

Wander
