Stratification for Confounding – Part 1: The Mantel-Haenszel Formula [PDF]

open access: yesNephron Clinical Practice, 2010
Stratification allows to control for confounding by creating two or more categories or subgroups in which the confounding variable either does not vary or does not vary very much. The Mantel-Haenszel formula is applied in cohort and in case-control studies to calculate an overall, unconfounded, effect estimate of a given exposure for a specific outcome

Multilevel Generalized Mantel-Haenszel for Differential Item Functioning Detection

open access: yesFrontiers in Education, 2019
Research has demonstrated that when data are collected in a multilevel framework, standard single level differential item functioning (DIF) analyses can yield incorrect results, particularly inflated Type I error rates.

Mantel-Haenszel Test Statistics for Correlated Binary Data [PDF]

open access: yesBiometrics, 1997
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 ...

Some Mantel‐Haenszel tests of Rasch model assumptions [PDF]

open access: yesBritish Journal of Mathematical and Statistical Psychology, 2001
A class of Rasch model tests is proposed, all of them based on the Mantel‐Haenszel chi‐squared statistic. All tests make use of the ‘sufficient statistics’ property the Rasch model possesses. One element of our general class, the test for item bias developed by Holland and Thayer, has been discussed extensively in the psychometric literature.
