On the Asymptotic Relative Efficiency of the Mantel‐Haenszel Test

Biometrical Journal, 1987
AbstractThe Mantel‐Haenszel test is optimal when the odds ratio is constant. This paper investigates the effects of departures from the assumption of a constant odds ratio on the behavior of the Mantel‐Haenzel test. A simple approximation is proposed for the non‐null distribution of the test statistic.

AN APPLICATION OF THE MANTEL-HAENSZEL STATISTIC IN PROCESS VALIDATION

Journal of Biopharmaceutical Statistics, 2005
Discrepancies in the data of a bioequivalence study led to questions about the procedures used in the analytical laboratory. In this article we describe some statistical and graphical procedures that were used to explore the causes of a process failure for an unvalidated process.

Extensions of Mantel–Haenszel for Multilevel DIF Detection

Educational and Psychological Measurement, 2013
Multilevel data structures are ubiquitous in the assessment of differential item functioning (DIF), particularly in large-scale testing programs. There are a handful of DIF procures for researchers to select from that appropriately account for multilevel data structures. However, little, if any, work has been completed to extend a popular DIF method to

Propriety of the Mantel-Haenszel Variance for the Log Rank Test

Biometrika, 1985
A challenge by \textit{M. Brown} [ibid. 71, 65-74 (1984; Zbl 0586.62061)] of the Mantel-Haenszel variance for the log rank test is dismissed as due to the nonasymptotic situation considered by Brown. Where the censoring mechanism in a time-to-response study could be influenced by treatment, the permutational variance is inappropriate and the Mantel ...

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 ...

Estimators of the Variance of the Mantel-Haenszel Log-Odds-Ratio Estimate

Biometrics, 1987
A new approach to large-sample studies of the variance of the log-odds- ratio estimate of \textit{N. Mantel} and \textit{W. Haenszel} [J. Nat. Cancer Inst. 22, 719-748 (1959)] is developed and used to derive formulas that lead to useful standard error formulas for the Mantel-Haenszel estimate. The variance estimator of \textit{J. Robins}, \textit{N. E.

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

A Simple Mantel–Haenszel Type Test for Noninferiority

Statistics in Biopharmaceutical Research, 2020
Randomized clinical trials designed to establish noninferiority of an experimental therapy as compared to a standard (active-control) therapy as measured by binomial proportions are being widely us...
