Description

Lawley multivariate range restriction correction.

Usage

lMvrrc(rcov, vnp, as_cor = TRUE)

Arguments

rcov

The covariance matrix of the restricted sample.

vnp

The covariance matrix of predictors explicitly used for selection. This matrix should be based on the the unrestricted population.

as_cor

This argument can be set to FALSE to return a covariance matrix.
