%description
Model based clustering using the multivariate multiple Scaled t (MST) and
multivariate multiple scaled contaminated normal (MSCN) distributions. The
MST is an extension of the multivariate Student-t distribution to include
flexible tail behaviors, Forbes, F. & Wraith, D. (2014)
<doi:10.1007/s11222-013-9414-4>. The MSCN represents a heavy-tailed
generalization of the multivariate normal (MN) distribution to model
elliptical contoured scatters in the presence of mild outliers (also
referred to as "bad" points) and automatically detect bad points, Punzo,
A. & Tortora, C. (2021) <doi:10.1177/1471082X19890935>.
