摘要
给出 2× 2表配对资料的边际分布齐性检验公式和两个 2× 2表配对资料的边际分布差值的比较 ,推导出边际概率分布的点估计及其协方差矩阵 ,由此导出大样本时的检验公式 ,得到边际分布齐性检验的方法和两个样本的 2×
This paper aims to find the test formulas for the marginal distribution in 2×2 table and Comparis on of the differences between the marginal probabilities with two 2×2 tables methods.It deriver the test methods based on the point estimations of the marginal proportions and the covariance matrix of the points estimations in 2×2 table.Results:To obtain the formulas of tests for homogeneity of the marginal distribution and comparison of the marginal distribution between two 2×2 tables.
