iniihg

Compute the moment estimate of the preference parameter of the IHG distribution.
This preliminary estimate is set as initial value within the optimization procedure for an IHG model
fitting the observed frequencies.

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.
