%description
Assess the significance of identified clusters and estimates the true
number of clusters by comparing the explained variation due to the
clustering from the original data to that produced by clustering a
unimodal reference distribution which preserves the covariance structure
in the data. The reference distribution is generated using kernel density
estimation and a Gaussian copula framework. A dimension reduction strategy
and sparse covariance estimation optimize this method for the
high-dimensional, low-sample size setting. This method is described in
Helgeson, Vock, and Bair (2021) <doi:10.1111/biom.13376>.
