Some adaptive distribution-free tests about location parameters of symmetric distributions are proposed for the one- and two-sample cases, The preliminary inferences in these adaptive schemes is to classify the underlying distributions as having light, medium, or heavy tails with a statistic that is essentially the range of the sample divided by the mean deviation from the sample median. If this inference suggests medium tails, a Wilcoxon-type test is used; for heavy tails, a median-type test is used. A modified Wilcoxon test (eliminating middle sample items) is proposed for light-tailed distributions and portions of its null distribution are tabulated. The favorable performance of these adaptive tests is demonstrated by a Monte Carlo study. |
