Hi, A client has asked for a series of pair-wise tests similar to Tukey's but using medians as opposed to means. The reason is that the distributions are highly right skewed. Are there such tests (I'm finding nothing) and if so, is there anything in R? Thanks, Walt ________________________ Walter R.
