假设我做了一个 Wilcoxon 符号秩配对检验,例如:
a<-c(1.1, 2.2, 3.3, 4.4, 5.5)
b<-c(1.6, 1.0, 3.9, 2.2, 3.7)
wilcox.test(a,b,paired=TRUE,conf.int=TRUE)
Wilcoxon signed rank test
data: a and b
V = 12, p-value = 0.3
alternative hypothesis: true location shift is not equal to 0
95 percent confidence interval:
-0.6 2.2
sample estimates:
(pseudo)median
0.8
我想知道如何解释sample estimates(pseudo) median 0.8?这个值是如何计算的?
