Abstract: A test is proposed for the model selection problem for multinomial data based on penalized phi-divergences. The use of penalized phi-divergences is motivated by the presence of zero frequencies. An application to the selection of models to classify individuals according to their social preferences, say, altruistic, cooperative, individualistic, competitive and aggressive, according to their behaviour in a decomposed game, is used to exemplify the proposed technique.
