AI总结:

本文提出了一种基于贝叶斯因子的共同效应模型证据合成方法,结合了频率学和贝叶斯证据的相互作用,并通过模拟和实际案例验证了方法的有效性。

摘要:

贝叶斯因子,作为假设检验的贝叶斯工具,正受到文献中越来越多的关注。与它们的频率学对手(p值或检验统计量)相比,贝叶斯因子具有概念上的优势,能够为原假设和备择假设提供证据,并且可以校准,使其不那么依赖于样本量。关于来自单个研究的贝叶斯因子的合成研究正受到越来越多的关注,主要是针对元分析中的固定效应模型。在本文中,我们回顾并提出结合多个研究中贝叶斯因子的方法,根据所可用信息的水平,重点在于共同效应模型。在此过程中,我们提供了关于频率学和贝叶斯证据之间相互作用的见解。我们通过模拟研究评估了所讨论方法的性能,并在积极心理学领域的一个示例中应用了这些方法。

英文摘要:

Bayes Factors, the Bayesian tool for hypothesis testing, are receiving increasing attention in the literature. Compared to their frequentist rivals ($p$-values or test statistics), Bayes Factors have the conceptual advantage of providing evidence both for and against a null hypothesis, and they can be calibrated so that they do not depend so heavily on the sample size. Research on the synthesis of Bayes Factors arising from individual studies has received increasing attention, mostly for the fixed effects model for meta-analysis. In this work, we review and propose methods for combining Bayes Factors from multiple studies, depending on the level of information available, focusing on the common effect model. In the process, we provide insights with respect to the interplay between frequentist and Bayesian evidence. We assess the performance of the methods discussed via a simulation study and apply the methods in an example from the field of positive psychology.
