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

1
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.
