Mantel-Haenszel test statistics for correlated binary data

This paper proposes two new Mantel-Haenszel test statistics for correlated binary dat in 2x2 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 strata. Confidence intervals are also obtained and compared to those from the test of Liang (1985, Biometrika 72, 678-682).
