相关系数主要有三种：Pearson相关系数、Spearman秩相关系数和Kendall τ相关系数。皮尔逊(Pearson)相关系数大家应该都知道，也应该有用到过。但是秩相关(Spearman)系数和τ相关(Kendall)系数大家或许不知道。我们这一篇就来聊聊这三个系数。

Ahmed, I'm not sure why you would want to do this, but the following provides some example code that does what you asked. This builds a correlation matrix with Pearson r's below the diagonal and Spearman rho's above the diagonal. *** BEGIN STATA CODE *** sysuse auto, clear local va...
We describe the various methods in this order: methods concerning (1) single parameters (e.g., testing the signifi- cance of a correlation), (2) two independent parameters (e.g., the difference between two independent correlations), (3) k independent parameters, where k ≥ 2 (e.g., ...
SubjectRe: st: RE: Rankit, pearson and polychoric correlations [was:Ordinal to interval assuming normality] DateWed, 22 Oct 2003 11:57:35 +0200 Dear Statalist and especially Nick Cox I think I have a solution to my problem. It is to loop over each level in my (`in') variable and...
If observations are not independent, they are related, and Pearson’s correlation is not an appropriate statistical test (although there are other measures of association that can be used when you have observations that are not independent). For example, if some of the 100 students were in a...
