%description
Model based clustering with spherical data using mixtures of elliptically
symmetric distributions, namely mixtures of spherical elliptically
symmetric projected Cauchy (SESPC) or mixtures of elliptically symmetric
angular Gaussian (ESAG) distributions. The relevant paper is: Perdikis T.,
Alharbi N. and Tsagris M. (2026). <doi:10.48550/arXiv.2605.27496>.
