Corrects a restricted validity coefficient for direct range restriction on the predictor using the standard Thorndike Case II expression.

Usage

correct_r_direct_range_restriction(
  r_restricted,
  range_restriction_ratio = NULL,
  u = NULL
)

Arguments

r_restricted

Restricted-sample validity coefficient.

range_restriction_ratio

Ratio of unrestricted to restricted predictor standard deviations. This is the preferred v0.4.0 name for the literature's u.

u

Legacy alias for range_restriction_ratio.

Value

Corrected validity coefficient.
