L'hétérogénéité est prise en compte par l'introduction d'une variable de fidélité  suggérée  par Guadagni and Little (1983). Ce modèle est appliqué sur des données scanner françaises. Au niveau part de marché, la qualité de l'ajustement est bonne mais les coefficients sont instables et dépendent des marques et des ménages sélectionnés ainsi que des choix techniques effectués pour l'initialisation des variables de fidélité."

This model is applied to a French scanner dataset. Quality of fit at aggregate level is good but coefficients are found to be dependent on brand selection, household selection, and technical choices for initialization of the loyalty variable."
