%description
Sequential outlier identification for Gaussian mixture models using the
distribution of Mahalanobis distances. The optimal number of outliers is
chosen based on the dissimilarity between the theoretical and observed
distributions of the scaled squared sample Mahalanobis distances. Also
includes an extension for Gaussian linear cluster-weighted models using
the distribution of studentized residuals. Doherty, McNicholas, and White
(2025) <doi:10.48550/arXiv.2505.11668>.
