A mixture model (denoted CUB) for ordinal data has recently been proposed in literature. Specifically, the ratings are presented bymeans of a mixture of a Uniform and a shifted Binomial random variable. This article illustrates a testing procedure for comparing CUB models which helps the interpretation of results in presence of complex surveys involving the evaluation of several items.

Abstract
A mixture model (denoted CUB) for ordinal data has recently been proposed in literature. Specifically, the ratings are presented bymeans of a mixture of a Uniform and a shifted Binomial random variable. This article illustrates a testing procedure for comparing CUB models which helps the interpretation of results in presence of complex surveys involving the evaluation of several items.File in questo prodotto:
