Abstract
The pair chart is known to be a convenient descriptive tool in comparing two samples and in calculating and interpreting various nonparametric procedures for the twosample problem (see Quade (1973)). To incorporate rightcensored data in the twosample problem, a generalized pair chart is considered and the same is utilized in the schematic computation of Gehan's Wstatistic (Gehan (1965)) and a triplet statistic (see Crouse and Steffens (1969)) among others. An alternative pair chart based on partial observations is also considered. A maximal distance statistic, based on the generalized pair chart, has been considered for testing the hypothesis of equality of the two distributions.
