经典的非参数置信区间的中位数差异或比例假设响应变量或对数转换响应变量的分布在每个种群中具有相同的形状。提出了不需要相同形状的分布的差异和中位数比率的无渐近分布置信区间。新的渐近方法易于计算，模拟结果表明它们在小样本中的性能很好。
The classic nonparametric confidence intervals for a difference or ratio of medians assume that the distributions of the response variable or the log-transformed response variable have identical shapes in each population. Asymptotic distribution-free confidence intervals for a difference and ratio of medians are proposed which do not require identically shaped distributions. The new asymptotic methods are easy to compute and simulation results show that they perform well in small samples.
