Clover plot: Versatile visualization in nonparametric classification*

Abstract

A versatile visualization tool that aggregates several classification techniques is proposed and studied. In the clover plot we combine four complementary classifiers-the depth-depth plot, the bagdistance plot, an approach based on the illumination, and the classical diagnostic plot based on Mahalanobis distances. An interactive R implementation of this tool, including several model examples of its use, is freely available online.
