Abstract
Good (1979, Biometrics 35, 483-489) introduced a new randomization test for the two-sample problem where a proportion 1-p of the treatment group does not respond to the treatment, and suggested that the Wilcoxon test is not effective for this situation. We show to the contrary that the Wilcoxon test is quite useful when p .gtoreq. .6 and point out an error in his definition of a one-tailed randomization test.This publication has 3 references indexed in Scilit:
