Scientific production on the Mantel-Haenszel procedure as a way of detecting DIF.
For more than two decades, the Mantel-Haenszel (MH) procedure has been used to detect differential item functioning (DIF). A bibliometric study of this use of the MH procedure was conducted in order to better understand the current state of the research activity in the area (in terms of quantitative indicators and impact). Initially, we drew up a map of scientific output about this research are...
متن کاملThe Mantel-Haenszel Procedure Revisited: Models and Generalizations
Several statistical methods have been developed for adjusting the Odds Ratio of the relation between two dichotomous variables X and Y for some confounders Z. With the exception of the Mantel-Haenszel method, commonly used methods, notably binary logistic regression, are not symmetrical in X and Y. The classical Mantel-Haenszel method however only works for confounders with a limited number of ...
متن کاملType I error and statistical power of the Mantel-Haenszel procedure for detecting DIF: a meta-analysis.
This article presents a meta-analysis of studies investigating the effectiveness of the Mantel-Haenszel (MH) procedure when used to detect differential item functioning (DIF). Studies were located electronically in the main databases, representing the codification of 3,774 different simulation conditions, 1,865 related to Type I error and 1,909 to statistical power. The homogeneity of effect-si...
متن کاملAn Illustration of a Mantel-Haenszel Procedure to Flag Misbehaving Common Items in Test Equating
In this study the Mantel-Haenszel procedure, widely used in studies for identifying differential item functioning, is proposed as an alternative to the delta-plot method and applied in a test-equating context for flagging common items that behave differentially across cohorts of examinees. The Mantel-Haenszel procedure has the advantage of conditioning on ability when making comparisons of perf...
متن کاملStratification for confounding--part 1: the Mantel-Haenszel formula.
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 by combining stratum-specific relative ris...
