%description
Parsimonious Ultrametric Gaussian Mixture Models via grouped coordinate
ascent (equivalent to EM) algorithm characterized by the inspection of
hierarchical relationships among variables via parsimonious extended
ultrametric covariance structures. The methodologies are described in
Cavicchia, Vichi, Zaccaria (2024) <doi:10.1007/s11222-024-10405-9>, (2022)
<doi:10.1007/s11634-021-00488-x> and (2020)
<doi:10.1007/s11634-020-00400-z>.
