%description
This is a modification of 'HDoutliers' package. The 'HDoutliers' algorithm
is a powerful unsupervised algorithm for detecting anomalies in
high-dimensional data, with a strong theoretical foundation. However, it
suffers from some limitations that significantly hinder its performance
level, under certain circumstances. This package implements the algorithm
proposed in Talagala, Hyndman and Smith-Miles (2019) <arXiv:1908.04000>
for detecting anomalies in high-dimensional data that addresses these
limitations of 'HDoutliers' algorithm. We define an anomaly as an
observation that deviates markedly from the majority with a large distance
gap. An approach based on extreme value theory is used for the anomalous
threshold calculation.
