基于R计算皮尔逊相关系数
函数
基本基本函数 cor.test
两组数据读入
x=read.csv("1.csv",header = T)
y=read.csv("2.csv",header = T)
计算
cor.test(1,2,method="pearson")
结果
Pearson's product-moment correlation
data: 1 and 2
t = 841, df = 34, p-value <0.0000000000000002
alternative hypothesis: true correlation is not equal to 0
95 percent confidence interval:
1 1
sample estimates:
cor
