varcovcubshe

Compute the variance-covariance matrix of parameter estimates of a CUB model with shelter effect.

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.
