PublicationBiasBenchmark (version 0.1.3)

method.pcurve: pcurve (P-Curve) Method

Description

Implements the p-Curve method which analyzes the distribution of p-values from significant studies to assess whether the significant findings reflect true effects or QRP/publication bias. The method also provides tests for the evidential value, lack of evidential value, and p-hacking. See simonsohn2014pcurve;textualPublicationBiasBenchmark for details.

The current implementation does not provide a test against the null hypothsis of no effect and does not produce confidence intervals of the estimate.
