Computes the percentage variance attributed to attenuating artifacts (sampling error, restriction of range, reliability in predictor and criterion.
A matrix or data.frame with columns Rxy, n and artifacts (Rxx, Ryy, u):
Logical test to determine if the approximate or exact var e is used
Percent of variance is computed as: (
varAV ) /
varr * 100
A numeric value representing the percent of variance accounted for by artifacts
