A Nonparametric “Trim and Fill” Method of Accounting for Publication Bias in Meta-Analysis
荟萃分析中校正发表偏倚的非参数“剪补法”
Meta-analysis collects and synthesizes results from individual studies to estimate an overall effect size. If published studies are chosen, say through a literature review, then an inherent selection bias may arise, because, for example, studies may tend to be published more readily if they are statistically significant, or deemed to be more “interesting” in terms of the impact of their outcomes. We develop a simple rank-based data augmentation technique, formalizing the use…
