Abstract : The paper proposes a rank test based on independent subexperiments for the comparison of a treatment effect with a control when the treatment is destructive in nature but the control produces at most a transient effect. The present work enhances the utility of the test in practical situations by providing a thorough study of its performance under two sampling situations. With the aid of a computer, the exact small sample power of the test is evaluated for some important alternatives. A modification of the test is proposed for the situation where numerical measurements are available rather than merely the ranks within each stage. The modification is found to substantially improve the power. Both the tests are shown to be unbiased. Finally, the Pitman asymptotic efficiencies are obtained and comparisons are made with the appropriate Wilcoxon tests. (Author)
