Description: 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.
