title: Estimators of the Mantel-Haenszel variance consistent in both sparse data and large-strata limiting models.
abstract: This paper proposes a new estimator of the variance of the Mantel-Haenszel estimator of common odds ratio that is easily computed and consistent in both sparse data and large-strata limiting models. Monte Carlo experiments compare its performance to that of previously proposed variance estimators.
