相对应的spearman correlation对异常值不敏感,因为它是属于rank test,具体见下面介绍。 spearman correlation coefficient(斯皮尔曼相关性系数-p) 通常也叫斯皮尔曼秩相关系数。 “秩”,可以理解成就是一种顺序或者排序,那么它就是根据原始数据的排序位置进行求解,而不是直接是用x,y的值进行求解(因此对异常值不敏感...
An online Spearman's Rho (correlation coefficient) calculator (offers scatter diagram, full details of the calculations performed, etc).
cor.test()函数就是使用t检验进行显著性检验的: cor.test(x, y) ## Pearson's product-moment correlation ## ## data: x and y ## t = 2.9397, df = 4,p-value= 0.0424 ## alternative hypothesis: true correlation is not equal to 0 ...

Spearman分析:揭秘等级相关 Spearman等级相关系数(Spearman's rank order correlation coefficient)是一种用于定序尺度(ordinal scale)数据的相关分析方法。它特别适用于两个变量都是等级尺度的情况,目的是衡量两组等级之间的一致性程度。 应用场景: 两个人对N台笔记本电脑的印象分数进行等级评定。 一个人对N台笔记本电脑...
Critical Values for Spearman’s Rank Correlation Coefficient Use this table to determine the significance of your result for this test. For example, if you had 20 pairs of data and a value of 0.53 then there would be a probability of between 0.01 and 0.005 that it had occurred by chan...
Interpreting the Results of the Spearman Correlation Coefficient Test Since the correlation (0.367) isn't 0.80 or greater, we cannot conclude there is a correlation between smoking and hypertension in these ten smokers. Note:In the example, above we havehiddenthe unused columns. Neverdeleterows or...
