在几种替代方法处理领带的方法下，给出了Wilcoxon签名秩检验的渐近效率的抽象公式。根据Wilcoxon提出的两种处理扎带的处理方法，另一种是由Pratt提出的，是根据它们的渐近效率进行了比较。在某些情况下，每种方法都比另一种方法更好。两个示例考虑了离散的均匀分布和二项式分布。
Abstract Formulas are given for asymptotic efficiency of the Wilcoxon signed-rank test under several alternative ways of handling ties. Two methods of handling ties at zero, one suggested by Wilcoxon and the other by Pratt, are compared on the basis of their asymptotic efficiencies. Each method is shown to be better than the other in some situations. Two examples consider the discrete uniform distribution and the binomial distribution.
