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...
the purpose of this study was to detect differentially functioning items in the university of tehran english proficiency test (utept) which is a high stake test of english developed and administered by the language testing centre of the university of tehran. this paper is based on the answers of 400 test takers to the test. all participants earned a master degree either in humanities or science...
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)
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 man...
