Nonparametric consistency for maximum likelihood estimation and clustering based on mixtures of elliptically-symmetric distributions

no code implementations10 Nov 2023 Pietro Coretto, Christian Hennig

The consistency of the maximum likelihood estimator for mixtures of elliptically-symmetric distributions for estimating its population version is shown, where the underlying distribution $P$ is nonparametric and does not necessarily belong to the class of mixtures on which the estimator is based.

Selecting the number of clusters, clustering models, and algorithms. A unifying approach based on the quadratic discriminant score

no code implementations3 Nov 2021 Luca Coraggio, Pietro Coretto

Based on bootstrap resampling of the quadratic scores, we propose a selection rule that allows choosing among many clustering solutions.
