.refine_var_rr: Range-restriction refinement factor (i.e., "a") for correlations' corrected sampling variances

Description

For use with Case II and Case IV range restriction (not for use with Case V).

Usage

.refine_var_rr(rxyi, ux, rxx = NULL, indirect_rr = rep(TRUE,
  length(rxyi)), ux_observed = rep(TRUE, length(rxyi)),
  rxx_restricted = rep(TRUE, length(rxyi)))

Arguments

rxyi

Vector of observed correlations.

ux

Vector of u ratios.

rxx

Vector of reliability estimates.

indirect_rr

Logical vector determining whether a correction for indirect range restriction was performed (TRUE) or not (FALSE).

ux_observed

Logical vector determining whether each element of ux is an observed-score u ratio (TRUE) or a true-score u ratio (FALSE).

rxx_restricted

Logical vector determining whether each element of rxx is an incumbent reliability (TRUE) or an applicant reliability (FALSE).

Value

A vector of range-restriction refinement factors.
