are evaluated by reference to the chi-square distribution. Its properties were first investigated by Karl Pearson. In contexts where it is important to make a distinction between the test statistic and its distribution, names similar to Pearson Χ-squared test or statistic are used.

mcnemar.test(X,correct=FALSE) # McNemar's Chi-squared test# data: X# McNemar's chi-squared = 4.0909, df = 1, p-value = 0.04311结论:p-value = 0.04311< 0.05,可以认为两种方法的检测结果不同。 3.3 mcnemar.test()函数 使用mcnemar.test()函数进行McNemar检验。 mcnemar.test(x, y=NULL, #...
常用方法:卡方同质性检验(Chi-squared test for homogeneity)是常用的同质性检验方法。 独立性检验(Independence test): 目的:检验两个分类变量之间是否存在关联或依赖关系。 应用场景:当你想要分析两个分类变量之间是否存在某种联系时使用。例如,检验性别(男性/女性)和职业选择(工程师/非工程师)之间是否存在关联。 常...
