Hi folks, sorry for this beginner question but what means a p-value = NA on
a menn-whitney test?
v1 <- c(0.022, 0.022, 0.022, 0.022, 0.022, 0.022)
v2 <- c(0.022, 0.022, 0.022, 0.022, 0.022)
wilcox.test(v1, v2, PAIRED=FALSE)
W = 15, p-value = NA
I know that there's no statistical difference between v1 and v2, so why my
p-value is not ONE ??
Can I consider p-value= NA as ONE ??
what i do when get this type of value on wilcox.test ???
PS: sorry for my bad english.
