[R] Multilevel analysis for ordinal responses

[Rune Haubo]

Yes; see clm and clmm2 (mixed effects) in the ordinal package for
fitting proportional odds models. See section 3 of
http://cran.r-project.org/web/packages/ordinal/vignettes/clm_tutorial.pdf
to see how to test the proportional odds assumption with clm - it is
equivalent for clmm2 models. For an introduction to clmm2, see
http://cran.r-project.org/web/packages/ordinal/vignettes/clmm2_tutorial.pdf.

Hope this helps,
Rune
