2×2设计中主效应与交互作用的分位数偏移方法

A Quantile Shift Approach To Main Effects And Interactions In A 2-By-2 Design

Rand R. Wilcox, Guillaume A. Rousselet

AI总结:

本文将分位数偏移函数扩展到2×2被试间设计,提出基于Harrell–Davis估计量与百分位置信bootstrap的两种主效应和交互作用分析方法,并通过模拟评估其假阳性与真阳性率。

摘要:

在比较两个独立组时,偏移函数本质上是比较多个分位数而非单一位置度量的技术,其目标是更详细地理解分布之间有何差异。已有多种版本被提出并研究。本文讨论如何将这些方法扩展到被试间×被试间的2×2设计中的主效应和交互作用。研究了两种方法:一种比较分布的十分位数,另一种与Wilcoxon–Mann–Whitney方法存在某种联系。对于这两种方法,我们提出使用Harrell–Davis分位数估计量的实现,并结合百分位置信bootstrap方法。我们报告了假阳性率和真阳性率的模拟结果。

英文摘要:

When comparing two independent groups, shift functions are basically techniques that compare multiple quantiles rather than a single measure of location, the goal being to get a more detailed understanding of how the distributions differ. Various versions have been proposed and studied. This paper deals with extensions of these methods to main effects and interactions in a between-by-between, 2-by-2 design. Two approaches are studied, one that compares the deciles of the distributions, and one that has a certain connection to the Wilcoxon-Mann-Whitney method. For both methods, we propose an implementation using the Harrell-Davis quantile estimator, used in conjunction with a percentile bootstrap approach. We report results of simulations of false and true positive rates.
