New statistical method generalizes underlap coefficient for multivariate group separation

Researchers have developed a generalized underlap coefficient (UNL) to quantify distributional separation across multiple groups in multivariate settings. This new measure is related to Bayes risk and mutual information, and can be interpreted as an indicator of dependence between group labels and variables of interest. An efficient estimator for the UNL is proposed, which can be combined with various density estimation methods. A primary application of this methodology is in clustering, where the UNL can assess how well latent group structures are explained by specific covariates. AI
