A modification of Mood's median test for the generalized Behrens-Fisher problem
广义 Behrens–Fisher 问题的 Mood 中位数检验修正
A modification of Mood's median test is described which allows one to test for differences between two medians without making any assumptions on the shapes of the underlying populations. The proposed procedure is exactly distribution-free when the populations have the same shape and is asymptotically distribution-free when they do not. It is the retention of the exact distribution-free property when the populations have the same shape which distinguishes the proposed…
