Marginal homogeneity 边际同质性 检验
In statistics, McNemar's test is a statistical test used on paired nominal data. It is applied to 2 × 2 contingency tables with a dichotomous trait, with matched pairs of subjects, to determine whether the row and column marginal frequencies are equal (that is, whether there is "marginal homogeneity"). It is named … See more The test is applied to a 2 × 2 contingency table, which tabulates the outcomes of two tests on a sample of N subjects, as follows.

WebThe marginal homogeneity test tests the equality of two multinomial c × 1 tables, and the data can be arranged in the form of a square c × c contingency table. A 2 × c table is constructed for each off-diagonal cell count. The marginal homogeneity test statistic is computed for cases with different values for the two variables. Web2 Answers. There is a clear difference between the two problems if you model them in the Bayesian way. In some papers the first case (homogeneity) is called sampling with "one margin fixed" and the second case (independence) as "total table fixed". Have a look, for example, at Casella et al. (JASA 2009).
