P-Curve Fixes Publication Bias: Obtaining Unbiased Effect Size Estimates from Published Studies Alone
Abstract
Journals tend to publish only statistically significant evidence, creating a scientific record that markedly overstates the size of effects. We provide a new tool that corrects for this bias without requiring access to nonsignificant results. It capitalizes on the fact that the distribution of significant p-values, p-curve, is a function of the true underlying effect. Researchers armed only with sample sizes and test results of the published...
