loglikcub00

Compute the log-likelihood function of a CUB model without covariates for a 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.
