中位数的确切可信区间

Exact Confidence Interval for the Median

Wilcoxon秩和检验和符号秩和检验常用于总体中心位置的假设检验。本文的主要目的是利用这二个检验的确切概率计算,建立中位数的确切可信区间。

Wilcoxon's rank sum test for unpaired observations and wilcoxon signed rank test for paired treatments are used to test the hypothesis that two populations have no difference for location. The primary purpose of this paper are to present the calculaton method of the exact confidence interval for the median. The procedure is relation to the exact probability of above two tests.
