Q2gecub

Define the opposite one of the two scalar functions that are maximized when running the E-M algorithm
for GeCUB models with covariates for feeling, uncertainty and overdispersion.

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.
