应按序数,区间或比率测量两个变量。 假定两个变量之间存在单调关系。 皮尔逊Pearson相关系数使用前提条件中,任何一个条件不满足时可以考虑使用该系数; Spearman与Pearson相关系数计算很类似,只是Spearman计算需要将两个变量转化为序数。 肯德尔tau-b相关系数

奈曼-皮尔逊(Neyman-Pearson)引理首先指出,在固定第一类错误的情况下,最有效力的检验是存在的。此外,奈曼-皮尔逊(Neyman-Pearson)引理告诉我们如何去构造这样的检验,而这样的检验就是似然比检验。 我们可以看这样一个例子。

所以,我们就可以知道, 两者的前提假设就不同,Pearson相关假设数据集在同一条直线上,而Spearman只要求单调递增或者递减(比如最常见的log scale单调变换),所以Pearson的统计效力比Spearman要高。. 我们要强调的是,Pearson相关系数要求 统计资料 要是 连续型变量 ...
Pearson相关系数是用来衡量两个变量之间线性相关程度的指标,取值范围在-1到1之间,其中0表示无相关,正值表示正相关,负值表示负相关。Pearson相关系数的平方即为 R^2 ,也被称为决定系数,表示一个变量能够被另一个变量解释的比例。
