In this paper we consider the problem of measuring the heterogeneity of a distribution of ratings in presence of 'don't know' responses, when data are fitted by a CUB model. We show that a preliminary adjustment of the model parameters, according to a recently proposed method for the treatment of 'don't know' responses, allows to correspondingly obtain an adjusted measure of heterogeneity.

Abstract
In this paper we consider the problem of measuring the heterogeneity of a distribution of ratings in presence of 'don't know' responses, when data are fitted by a CUB model. We show that a preliminary adjustment of the model parameters, according to a recently proposed method for the treatment of 'don't know' responses, allows to correspondingly obtain an adjusted measure of heterogeneity.File in questo prodotto:
