How to perform chi square test for goodness of fit in R - The chi square test for goodness of fit is a nonparametric test to test whether the observed values that falls into two or more categories follows a particular distribution of not. We can say that
For example, if you were rolling a fair six-sided die 60 times and wanted to test whether the frequencies of each number rolled match the expected frequencies (1/6 for each number), you could use a goodness-of-fit chi-square test. Test of Independence This test examines whether there is...
若考察二分类变量的分布是否服从假设分布,可以使用二项分布检验。如果类别数多于两类,可以使用卡方拟合优度检验(Chi-square goodness-of-fit test)。本文实例演示在SPSS软件中实现卡方拟合优度检验的操作过程。 关键词:SPSS; 卡方拟合优度检验; 二项分布检验;单样本卡方检验 ...
