Métodos de diagnóstico em modelos logísticos trinomiais

摘要: The trinomial logistic models can be interpreted as a natural extension of the traditional binomial model to situations in which response allows only three possible results. We first introduce and then some inferential aspects, such estimation hypothesis testing are discussed. Goodness-of-fit measures also given. However, aim this work is presentation diagnostic procedures for models. show that methods developed adapted straightforward development direct methods, even though possible, general requires more complex calculation. Some these evaluation residuals, high leverage points, deletion local influence presented. Comparisons between made via examples with real data.
