On the Poor Statistical Properties of the P -Curve Meta-Analytic Procedure
研究发现P曲线检验不具备声称的检测证据价值或左偏的能力，且不满足可接受性和单调性等基本要求，建议研究者停止使用该方法。
The P-curve is a widely used suite of meta-analytic tests advertised for detecting problems in sets of studies. They are based on nonparametric combinations of p values (e.g., Marden) across significant (p < .05) studies and are variously claimed to detect “evidential value”, “lack of evidential value”, and “left skew” in p values. We show that these tests do not have the properties ascribed to them. Moreover, they fail basic desiderata for tests, including admissibility and monotonicity. In light of these serious problems, we recommend against the use of the P-curve tests.
