The CORR Procedure

1 With Variables: wangjian
1 Variables: wangnei

Simple Statistics

Variable N Mean Std Dev Sum Minimum Maximum

wangjian 48 850062 518837 40802988 241673 1998261
wangnei 48 8135197 1872001 390489465 5611877 13050028

Pearson Correlation Coefficients, N = 48
Prob > |r| under H0: Rho=0

wangnei

wangjian 0.63163
<.0001（假设检验，在H0为两变量不相关的概率小于万分之一，因此两变量相关，相关系数为0.63）

可以设定检验方法，包括spearman hoeffding kendall
