%0 Journal Article %A Pardo Llorente, Leandro %A Menéndez Calleja, María Luisa %T On some pre-test and Stein-rule phi-divergence test estimators in the independence model of categorical data %D 2008 %@ 0378-3758 %U https://hdl.handle.net/20.500.14352/50255 %X For the model of independence in a two way contingency table, shrinkage estimators based on minimum phi-divergence estimators and phi-divergence statistics are considered. These estimators are based on the James-Stein-type rule and incorporate the idea of preliminary test estimator. The asymptotic bias and risk are obtained under contiguous alternative hypotheses, and on the basis of them a comparison study is carried out. %~
