二维列联表对角和的Bayes分析

Bayesian Analysis for Diagonal Sum in the 2×2 Table

研究了2×2列联表中对角和Bayes统计推断问题.在Dirichlet先验分布假设下,推导出对角和的后验分布,并对列联表对角和做了Bayes假设检验,并通过实例分析说明了方法的有效性.

2 ×2 table is widely apply in the education, clinical medicine, preventive medicine, biotechnology industry and so on. The article studies the Bayesian analysis for diagonal sum in 2 × 2 table. In the Dirchlet prior distribution, using the Bayesian method to derives the exact posterior distribution for diagonal sum.
