In psychmeta: Psychometric Meta-Analysis Toolkit

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.
