A Graphical Method for Detecting Multivariate Outliers

by Juan Carlos Correa and Victor Ignacio Lopez.

Abstract: A new graphical method is proposed to help us to uncover potential outliers in multivariate samples. The idea behind the method is to analyze the behavior of a growing neighborhood of each data point. This method is very robust and permits to find outliers in very complex structures.
