Generalization of the Mantel-Haenszel Estimator to Nonconstant Odds Ratios

Biometrics, 1985
\textit{N. Breslow} [ibid. 32, 409-416 (1976; Zbl 0339.62077)] proposed a model for stratified case-control data which allows variation of the odds ratio with variables used for stratification. He suggested using the conditional maximum likelihood estimator to estimate the parameters of the model. We propose a new estimator which is a generalization of

The Effects of Score Group Width on the Mantel‐Haenszel Procedure

Journal of Educational Measurement, 1994
Previous research examining the effects of reducing the number of score groups used in the matching criterion of the Mantel‐Haenszel procedure, when screening for DIF, has produced ambiguous results. The goal of this study was to resolve the ambiguity by examining the problem with a simulated data set.

Two New Approaches to Assessing Differential Item Functioning: Standardization and the Mantel--Haenszel Method

, 1989
The standardization and Mantel-Haenszel approaches to the assessment of differential item functioning (DIF) are described and compared. For rightwrong scoring of items, these two approaches, which emphasize the importance of comparing comparable groups ...

The Effect of Missing Data Treatment on Mantel-Haenszel DIF Detection

Alberta Journal of Educational Research, 2011
Most implementations of the Mantel-Haenszel differential item functioning procedure delete records with missing responses or replace missing responses with scores of 0.

On the small-sample properties of the Mantel-Haenszel test for relative risk

Biometrika, 1974
SUMMARY For the analysis of combinations of 2 x 2 contingency tables Cochran (1954) and also Mantel & Haenszel (1959) proposed related statistics for the null hypothesis that the relative risk i/ has the value unity from table to table. Using the model with constant effects on a logistic scale of probabilities (e.g. Cox, 1970), this paper presents some

Adjustments to the Mantel-Haenszel chi-square statistic and odds ratio variance estimator when the data are clustered.

Statistics in Medicine, 1987
Dependence between observations on a dichotomous variable renders invalid the usual chi-square tests of independence and inflates the variances of parameter estimates.

The Power of the Mantel-Haenszel Test for Grouped Failure Time Data

Biometrics, 1993
The Mantel-Haenszel test for grouped failure time data (MHF test) compares the distribution of failure times in two cohorts followed for an interval of time when the data are collected in discrete subintervals. This paper derives approximations to the power of the Mantel-Haenszel test for arbitrary failure time distributions in the presence of ...

Mantel-Haenszel-type inference for cumulative odds ratios with a stratified ordinal response.

Biometrics, 1996
This article proposes a Mantel-Haenszel-type estimator of an assumed common cumulative odds ratio in a proportional odds model for an ordinal response with several 2 x c contingency tables.

Conditional Independence, the Mantel-Haenszel Test, and the Yates Correction

The American Statistician, 2000
Abstract The Yates correction is often recommended as a means of improving the chi-squared approximation to the Pearson goodness-of-fit statistic in 2 × 2 tables. This article demonstrates that it is also needed for some conditional independence models in multiway tables containing two dichotomies.
