Abstract

The classical theory for the meta-analysis of pp-values is based on the assumption that if the overall null hypothesis is true, then all pp-values used in a chosen combined test statistic are genuine, i.e., are observations from independent and identically distributed standard uniform random variables. However, the pressure felt by most researchers to publish, which is worsen by publication bias, can originate fake pp-values to be reported, usually Beta(1,2) distributed. In general, the existence of fake pp-values in a sample of pp-values to be combined is unknown, and if, for some reason, there is information that they do exist, their number will most likely be unknown as well. Moreover, even if fake pp-values are accounted for, the cumulative distribution function of classical combined test statistics does not have a closed-form expression that facilitates its practical usage. To overcome this problem, tables with estimated critical values are supplied for the commonly used combined tests for the meta-analysis of pp-values when a few of them are fake ones, i.e., Beta(1,2) distributed.
