Mann-Whitney (Wilcoxon) and Kruskal-Wallis FAIL to compare medians in general. Quantile regression should be used to compare medians instead
# Let's make some data to play with
set.seed(1234)
v1 <- rexp(500)
v2 <- rnorm(500) + log(2)
v3 <- -rgamma(500, 2.5, 3)
v4 <- runif(500, -2,4)
# Look at the data
layout(matrix(c(1:4), nrow = 2))
