JohnHendrickx/Perturb: Tools for Evaluating Collinearity
Use the perturb() function to evaluates collinearity by adding random noise to selected variables (Hendrickx & Pelzer 2004). Version 3.0 of perturb() can be used with mixed models by nlme and lme4 (Hendrickx 2018). The colldiag function() calculates condition numbers and variance decomposition proportions to test for collinearity and uncover its sources (Belsley 1980).
