"""Regression Models for Ordinal Data.
Implementation of cumulative link (mixed) models also known as ordered
regression models, proportional odds models, proportional hazards models
for grouped survival times and ordered logit/probit/... models. Estimation
is via maximum likelihood and mixed models are fitted with the Laplace
approximation and adaptive Gauss-Hermite quadrature. Multiple random effect
terms are allowed and they may be nested, crossed or partially
nested/crossed. Restrictions of symmetry and equidistance can be imposed on
the thresholds (cut-points/intercepts). Standard model methods are
available (summary, anova, drop-methods, step, confint, predict etc.) in
addition to profile methods and slice methods for visualizing the
likelihood function and checking convergence."""
