... A Convex Hull Peeling Depth Approach to Nonparametric Massive Multivariate Data Analysis with Applications . Abstract: We explore the convex hull peeling process to develop empirical tools for statistical inferences on multivariate massive data. ... We define the convex hull peeling depth, which enables to order multivariate data. ... In addition to these empirical descriptive statistics, we find a few methodologies to separate multivariate outliers in massive data sets. ... Presentation [.pdf] . ...
