Generalized Cochran-Mantel-Haenszel Test Statistics for Correlated Categorical Data
نویسندگان
چکیده
S Three new test statistics are introduced for correlated categorical data in strati ed R C tables. They are similar in form to the standard generalized Cochran-Mantel-Haenszel statistics but modi ed to handle correlated outcomes. Two of these statistics are asymptotically valid in both many-strata (sparse data) and large-strata limiting models. The third one is designed speci cally for the many-strata case but is valid even with a small number of strata. This latter statistic is also appropriate when strata are assumed to be random.

A new approach for differential item functioning detection using Mantel-Haenszel methods. The GMHDIF program.
To date, the statistical software designed for assessing differential item functioning (DIF) with Mantel-Haenszel procedures has employed the following statistics: the Mantel-Haenszel chi-square statistic, the generalized Mantel-Haenszel test and the Mantel test. These statistics permit detecting DIF in dichotomous and polytomous items, although they limit the analysis to two groups. On the con...
متن کاملMantel-Haenszel test statistics for correlated binary data.
This paper proposes two new Mantel-Haenszel test statistics for correlated binary data in 2 x 2 tables that are asymptotically valid in both sparse data (many strata) and large-strata limiting models. Monte Carlo experiments show that the statistics compare favorably to previously proposed test statistics, especially for 5-25 small to moderate-sized strata. Confidence intervals are also obtaine...

The coin package implements a unified approach for conditional inference procedures commonly known as permutation tests. The theoretical basis of design and implementation is the unified framework for permutation tests given by Strasser and Weber (1999). For a very flexible formulation of multivariate linear statistics, Strasser and Weber (1999) derived the conditional expectation and covarianc...

متن کاملGeneralized Mantel-Haenszel Procedures for 2 × J Tables
Generalization of Mantel-Haenszel procedure for 2 x J (J > 2) tables is reviewed. Included are generalized Mantel-Haenszel tests, estimators for a common odds ratio, and generalized Breslow-Day test for the homogeneity of odds ratios across the strata.-Environ Health Perspect 102(Suppl 8): 57-60 (1994)
