Bahadur Efficiency of Two-Sample Tests Based on One-Sample Sign Statistics
基于单样本符号统计量的两样本检验之Bahadur效率
SUMMARY This paper discusses the two-sample test of location based on the comparison of two distribution-free one-sample confidence intervals derived from sign statistics. This test procedure, first introduced by Hettmansperger (1984), rejects the null hypothesis of equal population medians when the two intervals are disjoint. He presents three different ways to select the two one-sample intervals and one choice leads to Mood's test. All solutions have the same Pitman…
