Il problema dell'indeterminatezza nei modelli con variabili latenti

Abstract

This paper deals with a crucial problem of models with latent variables, the indeterminacy of the latent variables. Indeterminacy of the latent variables has the consequence that it is in most cases impossible to attach a real meaning to this variables. Particularly the common factor analysis model, models with error in the variables and the Lisrel model are analysed. An alternative method which resolves the indeterminacy of the latent variables is presented.
