卡方分布在统计学中的重要性无需多言,无论在参数和非参数统计领域上都有着相当重要的占比。著名的Kruskal-Wallis(ANOVA的非参数版本)/Conover(Bartlett的非参数版本)/Bartlett/Contingency Table/单方差测试等等都需要用到卡方分布。无中心卡方分布更是金融学中CIR模型的根本。 然而,卡方分布的推导过程极其繁琐(涉及到...

where each yi is independently sampled from a standard normal distribution and «dof» = n - 1 . The distribution is defined over nonnegative values. The Chi-squared distribution is commonly used for analyses of second moments, such as analyses of variance and contingency table analyses. ...
Compare the calculated Chi-Square statistic with the critical value from the Chi-Square distribution table; if it's more significant, reject the null hypothesis. 8. What is the advantage of the Chi-Square Test? The Chi-Square test is simple to calculate and applies to categorical data, making...
