The Rank-Score Test - an Improvement of the Rank-Sum Test.

Abstract

The hypothesis that two random samples are from identically distributed but unknown populations can be tested by use of the rank-sum as the test statistic. It is proposed to substitute for it the rank-score, which, as pointed out, supplies more information about the populations of the samples under examination. This new statistic is defined and its main properties are indicated. Tables for its application to pseudo-standardized samples have been established by use of two computer programs, thereby enabling tests of the hypothesis that the samples are from populations with identical distribution function, including its shape parameter, if any, but possibly different scale and location parameters. The practical use of the new test has been demonstrated by numerical examples concerning samples of fatigue test data from a large collection prepared at The Boeing Company. (Author)
