Regression Models for Ordinal Data
Description
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.
