New 'Polar Depth' measure aids analysis of extreme data

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new statistical measure called Polar Depth, designed to analyze extreme values in multivariate heavy-tailed distributions. This novel concept, expressed in polar coordinates, aids in ordering extreme observations and has applications in anomaly detection. The study demonstrates its properties and estimation challenges, with numerical results supporting its relevance for identifying anomalies. AI

    Polar Depth for Potentially Heavy-Tailed Data

    arXiv:2606.00343v1 Announce Type: cross Abstract: Motivated by the analysis of the behaviour of extremes from multivariate heavy-tailed distributions, we introduce a novel notion of statistical depth, referred to as Polar Depth. The polar depth function is naturally expressed in …
