Abstract

In this paper we consider a controversy on the use and interpretation of p-values in applied research. In recent years several applied and theoretical journals have started to discuss on the appropriate use of p-values in research fields such as Psychology, Ecology, and Medicine. First, the notion of p-value has some intrinsic limitations, which have been already highlighted in the statistical literature, but are far from being recognized in applied research. Second, it has emerged the so-called practice of p-hacking, which consists in analyzing and re-analyzing data until obtaining a significant result in terms of a p-value less than 0.05. In the light of these problems, we review two alternative theoretical frameworks, given by the use of Bayes factor and a recent proposal that leads to evaluate statistical hypotheses in terms of a priori and a posteriori odds ratios.
p值在应用研究中的应用:解释和新趋势
本文讨论了应用研究中关于p值的使用和解释的争议。近年来,一些应用和理论期刊开始讨论p值在心理学、生态学和医学等研究领域的适当使用。首先,p值的概念有一些内在的局限性,这些局限性在统计文献中已经得到了强调,但在应用研究中还远远没有得到认可。其次,出现了所谓的p黑客行为,即对数据进行分析和重新分析,直到获得p值小于0.05的显著结果。鉴于这些问题,我们回顾了两种可供选择的理论框架,它们是由贝叶斯因子的使用和最近的一项建议给出的,该建议导致根据先验和后验比值比评估统计假设。
