selection (version 1.0)

caseIV: Correct x/y correlations using Case IV

Description

caseIV uses Hunter and Schmidt's (2004) correction procedure to estimate the correlation between t and p, assuming direct selection on a latent s.

Usage

caseIV(rtpi, rxxi, rxxa, ux)

Arguments

rtpi

the correlation between t and p in the incumbent pool.

rxxi

the reliability of x in the incumbent pool.

rxxa

the reliability of x in the applicant pool.

ux

the ratio of selected to unselected variance in x.

Value

• a scalar that is the estimate of the correlation between t and p.

Examples

# correct an xy correlation for unreliability
	rtpi = rel.correction(rxyi=.3, rxxi=.8, ryyi=.6)
