cubp0

Estimate and validate a CUB model for given ordinal responses, with covariates for explaining
the feeling component via a logistic transform.

internal

For ordinal rating data, estimate and test models within the family of CUB models and their extensions (where CUB stands for Combination of a discrete Uniform and a shifted Binomial distributions); Simulation routines, plotting facilities and fitting measures are also provided.
