loglikcubshe

Compute the log-likelihood of a CUB model with a shelter effect
for the given absolute frequency distribution.

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.
