著名的McNemar检验评估了二进制配对数据中两个相关比例之间的差异。为了提高麦克内马尔测试的力量,并将其扩展到相关的问题,我们重新解释贝叶斯框架中的测试。用更真实的密度代替先前的密度实现了强大的测试。我们数值研究了不同的选择的先验密度,这强烈地影响了衍生测试的性能。此外,我们比较了建议的测试与现有的测试的最大实际水平。所提出的测试是有利的,其广泛的扩展性。我们通过一种与现有方法有很大不同的方法将来自多个地层的证据联合收割机结合起来。检验统计量是多个分层中替代模型的后验概率的乘积。所提出的测试在实际的例子中进行了验证。版权所有© 2016约翰威利父子有限公司.
The well‐known McNemar test assesses the difference between two correlated proportions in binary matched‐pairs data. To improve the power of the McNemar test and extend it to related problems, we reinterpret the test in a Bayesian framework. Replacing the prior density by a more realistic one realizes a powerful test. We numerically investigate different choices of the prior density, which strongly affects the performance of the derived test. Furthermore, we compare the maximum actual levels of the proposed test with those of existing tests. The proposed test is advantageous for its wide extendibility. We combine the evidence from multiple strata by an approach that largely differs from existing methods. The test statistic is the product of the posterior probabilities of the alternative models in the multiple strata. The proposed test is validated in practical examples.
