Comparison of the efficiency of nonparametric location tests based on grouped and individual data


  • Hüsler, J.
  • Riedwyl, H.


The efficiency of rank tests for the location in the one and two sample case based on grouped data is compared with the Wilcoxon signed-rank test and with the Mann-Whitney-Wilcoxon test respectively. These efficiencies are calculated for some Box-Tiao densities and different numbers of groups. It shows that the rank tests with a grouping of the data into 8 to 14 groups is for large samples as efficient as the ungrouped rank tests, and in addition that they are more efficient than the ungrouped rank tests if the underlying density has large tails.
