A Wilcoxon-type test for trend

Stat Med. Jan-Mar 1985;4(1):87-90. doi: 10.1002/sim.4780040112.

Abstract

An extension of the Wilcoxon rank-sum test is developed to handle the situation in which a variable is measured for individuals in three or more (ordered) groups and a non-parametric test for trend across these groups is desired. The uses of the test are illustrated by two examples from cancer research.
