ICS_ucov

ICS_scov

Wrapper functions for the one-step M-estimator of scatter with weights based
on Mahalanobis distances as computed by <code>scov()</code>, or the simple
related estimator that is based on a transformation as computed by
<code>ucov()</code>.

Implementation of tandem clustering with invariant coordinate
selection with different scatter matrices and several choices for the
selection of components as described in Alfons, A., Archimbaud, A., Nordhausen, K.and Ruiz-Gazen, A. (2024) <doi:10.1016/j.ecosta.2024.03.002>.
