Regression Models for Ordinal Data.
http://cran.r-project.org/web/packages/ordinal
This package implements likelihood based models for ordinal (ordered categorical) data based on cumulative probabilities in the framework of cumulative link models. This includes the important proportional odds model but also allows for general regression structures for location as well as scale of the latent distribution, i.e. additive as well as multiplicative structures, structured thresholds (cut-points), nominal effects and flexible link functions. Further, a range of estimation procedures and a range of auxiliary functions are implemented.
