基于秩方法的列联表数据独立性检验

摘要

Contingency table test is an important part of the independence of the inspection, the χ2 test is commonly used in elementary textbooks, which is relatively conservative.This paper addresses two different alter-native hypothesis, taking different methods of construction rank statistics to test, and illustrates that under the con-dition of adequate priori knowledge, the test is more effective thanχ2 .%列联表检验是独立性检验的一个重要内容，在初等教材中常用的是χ2检验，这是一种比较保守的检验法。针对有序和无序两个不同的对立假设，用秩方法构造不同的统计量进行检验，并通过实际例子说明了在先验知识比较充足的条件下，该检验法比χ2检验法有效。
