Marginal homogeneity 检验
WebIf that is the case, then the contingency table is said to display marginal homogeneity. Several real-life examples where marginal homogeneity is studied are given by Krauth (1986). A test for marginal homogeneity is proposed by Stuart (1955) and Maxwell (1970).

WebMar 3, 2005 · More generally, this and other models that we consider can incorporate explanatory variables in addition to the group. Model is simple. However, maximum likelihood (ML) fitting is computationally impractical for large c.The models apply to c marginal distributions of the 2 c-table for each group, yet the product multinomial … Webthere is marginal homogeneity. Also, for the 2 by 2 tables, when PI. = P.1o then Pt2 = PzI and the marginal homogeneity is equivalent to symmetry of the probabilities across the main diagonal. For this case, we may be interested in testing the hypothesis Ho: PI. = P.l or equivalently Ho: PI2 = Pal. An appropriate test to apply to
WebPart 3: Testing. If you are only interested if the overall distribution changed (i.e. if the percentages from each category changed or not), you can perform a marginal homogeneity test. There are two that seem to be quite popular for this, the Stuart-Maxwell test (Stuart, 1955; Maxwell, 1970), and the Bhapkar test (Bhapkar, 1966). WebIf marginal homogeneity holds, then the difference between the likelihood ratio statistics for the symmetry and quasi-symmetry models should have a chi-squared distribution with …

WebMarginal homogeneity means the row and column distributions (of a square table) are the same. That is, μ i + = μ + i. for all i. There is no log-linear model that corresponds directly to marginal homogeneity, but we can use the log-linear models of symmetry and quasi-symmetry to indirectly test for marginal homogeneity. 飯 レビューWebMarginal homogeneity means the row and column distributions (of a square table) are the same.

This test is an extension of the McNemar test from binary response to multinomial response. It tests for changes in response (using the chi-square distribution) and is useful for detecting response changes due to experimental intervention in before-and-after designs. ... 飯 レタリング
