Sensitivity Analysis in Canonical Analysis of Contingency Tables by Maximum Likelihood

概要

論文の詳細を見る
The results of a sensitivity analysis of a canonical analysis by maximum likehood of a contigency table (Gilula and Haberman, 1986) are presented. The approach to influence is from Cook and Weisberg (1982). The concept 'influential' depends on the perturbation pattern. In one example using various perturbation patterns the effects are evident on the estimates but from an interpretative viewpoint there is no drastric change, and so the model and its estimation method produce stable scorning representations. However, on the goodness of fit (X^2) there are important changes.
