%description
A clustering algorithm similar to K-Means is implemented, it has two main
advantages, namely (a) The estimator is resistant to outliers, that means
that results of estimator are still correct when there are atypical values
in the sample and (b) The estimator is efficient, roughly speaking, if
there are no outliers in the sample, results will be similar to those
obtained by a classic algorithm (K-Means). Clustering procedure is carried
out by minimizing the overall robust scale so-called tau scale. (see
Gonzalez, Yohai and Zamar (2019) <arxiv:1906.08198>).
