likelihood ratio chi-square test

A Dictionary of Psychology | Date: 2001

likelihood ratio chi-square test n. A statistical test of association or goodness of fit (1) that is based on the likelihood ratio (1) and is thought by many statisticians to be preferable to the conventional Pearson chi-square test for the simultaneous analysis of several overlapping associations in a multiple-classification table, because under certain conditions it has the property of additivity of effects. The statistic, which is distributed like chi-square, is computed from the natural logarithms of observed and (in goodness of fit tests) expected frequencies. Compare Pearson chi-square test.

Mayo Clinic Proceedings; 4/1/2005; Kohn, Michael A; Michaels, Andrew D; Bailey, Kent R; Weissler, Arnold M; Et al; 787 words ; To the Editor: The critique of likelihood ratio reporting by Weissler and Bailey1 assumes that likelihood ratios are reported for dichotomous tests. Doesn't it make sense to use a definition of the likelihood ratio that works generally for all types of tests, not just dichotomous tests? Most tests, Read more

Nonparametric likelihood ratio estimation of probabilities for truncated data.
Journal of the American Statistical Association; 9/1/1995; Li, Gang; 787 words ; 1. INTRODUCTION Truncated data is common in actuarial, demographic, epidemiologic, and other studies. Let (X, Y) be a pair of positive random variables with cumulative distribution functions [F.sub.0] and [G.sub.0]. We say that X is left truncated by Y (and thus Y is right truncated by X) if the Read more
