[R-pkgs] pivmet 0.2.0 - Pivotal Methods for Bayesian Relabelling and k-Means Clustering
The new version (0.2.0) of rhe 'pivmet' package is released on CRAN: https://CRAN.R-project.org/package=pivmet. The package offers a collection of pivotal algorithms for: relabelling the MCMC chains in order to undo the label switching problem in Bayesian mixture models, as proposed in Egidi et al. (2018a); initializing the centers of the classical k-means algorithm in order to obtain a better clustering solution (Egidi et al., 2018b). The new version incorporates the Stan language for fitting efficient mixture models. github package page at: https://github.com/LeoEgidi/pivmet Here are the two referred articles: Egidi et al.
