perturb: Tools for Evaluating Collinearity
Use the perturb() function to evaluates collinearity by adding
random noise to selected variables (Hendrickx & Pelzer 2004). The colldiag
function() calculates condition numbers and variance decomposition proportions
to test for collinearity and uncover its sources (Belsley 1980).
