Abstract
A mixture model for ordinal data modelling (denoted CUB) has been recently proposed in literature. Specifically, ordinal data are represented by means of a discrete random variable which is a mixture of a Uniform and shifted Binomial random variables. This article proposes a testing procedure for comparing CUB models which helps to detect similarities in the structure of judgements that raters express on set of items.File in questo prodotto:
