loglikcubp0

Compute the log-likelihood function of a CUB model fitting ordinal responses with covariates
for explaining the uncertainty component.

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.
