rhoCA {psychometric}

Meta-Analytically Derived Correlation Coefficient Corrected for Artifacts

Description

This represents the population correlation coefficient free from attenuaton due to artifacts (sampling error, range-restriction, reliability in the predictor and criterion).

Usage

rhoCA(x)

Arguments

x

A matrix or data.frame with columns Rxy, n and artifacts (Rxx, Ryy, u): see EnterMeta

Details

This is the sample weighted correlation coefficient rbar divided by the compound attenuation factor, CAFAA.

Value

A numeric value represting the corrected correlation coefficient.
