The evaluation of educational services, as well the analysis of judgements and preferences, poses several methodological challenges because of one or more aspects: the observational nature of the context, the hierarchical structure of the data, the multivariate and qualitative nature of the dependent variables, the presence of non observable factors, an so on. These circumstances strongly ask for the introduction of mixture models and this contribution surveys the main problems and issues related to statistical and computational point of views.

Abstract
The evaluation of educational services, as well the analysis of judgements and preferences, poses several methodological challenges because of one or more aspects: the observational nature of the context, the hierarchical structure of the data, the multivariate and qualitative nature of the dependent variables, the presence of non observable factors, an so on. These circumstances strongly ask for the introduction of mixture models and this contribution surveys the main problems and issues related to statistical and computational point of views.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
