Compound Attenuation Factor for Meta-Analytic Artifact Corrections

Description

The compound attenuation factor is computed as the product of the mean for each artifact distribution (square root of artifact) when correcting for attenuation in a correlation coefficient.

Usage

CAFAA(x)

Arguments

x	A matrix or data.frame with columns Rxx, Ryy, and u: see EnterMeta

Details

The compound attenuation factor is computed as the product of mean(a)*mean(b)*mean(c) where
a = sqrt(Rxx) and is computed with the function aRxx
b = sqrt(Ryy) and is computed with the function bRyy
c = sqrt((1-u^2)*rbar^2+u^2) and is computed with the function cRR

Value

A numeric value representing the compound attenuation factor

Note

This value is used in the correction for artifacts of a correlation coefficient
