This is to announce the new R-package ‘ordinal’ that implements cumulative link (mixed) models for ordinal (ordered categorical) data (http://www.cran.r-project.org/package=ordinal/).

The main features are:
- scale (multiplicative) as well as location (additive) effects

Future additions will include:
- more general random effect structures: multiple (crossed and nested)
and vector-valued random effects.
- profile methods for variance parameters in mixed effect models.

Comments, critique, suggestions, wishes and contributions are always highly appreciated.

Kind regards
Rune
