For paired binary data, McNemar's test is widely used to test marginal homogeneity or symmetry for a 2 by 2 contingency table. In this article, we extend McNemar's test by considering a series of paired binary data in which the series is defined by a stratification factor. We provide a test for testing homogeneous stratum effects. For illustration, we apply our test to a cancer epidemiology study. Finally, we conduct simulations to show that our test preserves the nominal type I error level and evaluate the power of our test under various scenarios.
对于配对二元数据，McNemar检验被广泛用于检验2×2列联表的边际同质性或对称性。在本文中，我们通过考虑一系列由分层因素定义的配对二元数据来扩展McNemar检验。我们提供了一种检验同质性分层效应的方法。为了说明，我们将我们的检验应用于一项癌症流行病学研究。最后，我们进行模拟以表明我们的检验保持了名义I型错误水平，并在各种情况下评估了我们检验的功效。
