Supplemental Materials for Visualizing Tests for Equality of Covariance Matrices

This page is intended to serve as an accompaniment to a paper prepared by Dr. Michael Friendly (@friendly) and Matthew Sigal (@mattsigal). The article pertains to the testing for equality of and visualization of covariance matrices in multivariate designs.

R code is provided throughout the article with commentary, and is provided here in fully reproducible form. The code is divided into 4 files: one for each primary example, and one for the work with betadisper().

Dataset/Topic R Script Rendered HTML
Iris iris-ex.R iris-ex.html
Wine wine-ex.R wine-ex.html
Skulls skulls-ex.R skulls-ex.html
betadisper betadisp-ex.R betadisp-ex.html

Questions and commentary can be directed to either @friendly or @mattsigal.
