effe01

Compute the opposite of the scalar function that is maximized when running
the E-M algorithm for CUB models with covariates for the feeling parameter.

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.
