sign_rxz = 1, sign_ryz = 1)

## Arguments

rtpa

Correlation corrected for range restriction and measurement error.

qxa

Vector of square-root of applicant reliability coefficients for X.

qya

Vector of square-root of applicant reliability coefficients for Y.

ux

Vector of observed-score u ratios for X.

uy

Vector of observed-score u ratios for Y.

sign_rxz

Sign of the relationship between X and the selection mechanism.

sign_ryz

Sign of the relationship between Y and the selection mechanism.

## Value
