检验多样本中位数的相等性

Testing Equality of Medians for Multiple Samples

Swapnaneel Bhattacharyya

AI总结:

针对多样本中位数相等性检验,本文提出一种一致非参数方法,并推广至位置参数及任意分位数,辅以理论证明与模拟验证。

摘要:

本文在每个样本内观测值独立同分布的条件下,构建了一种用于检验不同样本总体中位数相等性的一致非参数检验。该检验还可进一步用于检验不同样本的未知位置参数是否相等。本文讨论的方法可以从中位数推广到任意分位数水平。文中给出了理论结果,并通过模拟研究展示了该检验的性能。

英文摘要:

In this paper, we construct a consistent non-parametric test for testing the equality of population medians for different samples when the observations in each sample are independent and identically distributed. This test can be further used to test the equality of unknown location parameters for different samples. The method discussed in this paper can be extended to any quantile level instead of the median. We present the theoretical results and also demonstrate the performance of this test through simulation studies.
