Details

Defined as z = (0.5 - p) 12kz = (0.5 - mean(p)) * sqrt(12k) which is a standard normal and due to edgington72b;textualmetap becker94metaprosenthal78metap

The values of p_i should be such that 0 p_i 1 and a warning is given if that is not true. A warning is given if, possibly as a result of removing illegal values, fewer than four values remain and the return values are set to NA.

The plot method for class ‘metap’ calls plotp on the valid \(p\)-values.
