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 (mixed)
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, flexible link functions and
random effects. Further, a range of estimation procedures and a
range of auxiliary functions are implemented.
