Abstract

In first place a decomposition of the l.r.t. (likelihood ratio test) statistic to test the independence between a set of variables and a given number of other sets of variables into a number of independent l.r.t. statistics is presented. This decomposition induces a decomposition of the null hypothesis for this test, which allows for a different view over the test. Then, based on this decomposition, a double decomposition of the l.r.t. statistic to test the independence of m sets of variables is presented which itself induces a double decomposition of the null hypothesis of independence among m sets of variables which in turn allows for a different view and interpretation of this test. These decompositions are much useful in helping us to relate these tests and interpret them under a modeling point of view.
