Computes Edgington's p-value

The combined p-value with Edgington's method is computed based on the one-sided p-values (or the corresponding the z-values) of the original and replication study, and the ratio of the weight of the replication study over the weight of the original study

pEdgington(zo = NULL, zr = NULL, po = NULL, pr = NULL, r = 1)

Arguments

zo

A vector of z-values from original studies.

zr

A vector of z-values from replication studies.

po

A vector of one-sided original p-values.

pr

A vector of one-sided replication p-values.

r

Numeric vector of ratios of replication to original weight

Value

Edgington's p-value

Details

Either zo and zr, or po and pr, must be specified.
