mclustAddons

An R package extending the functionality of the mclust package (Scrucca et al. 2016, 2023) for Gaussian finite mixture modeling by including:

• density estimation for data with bounded support using a transform-based approach to Gaussian mixture density estimation (Scrucca, 2019);

• modal clustering using modal EM algorithm for Gaussian mixtures (Scrucca, 2021);

• entropy estimation via Gaussian mixture modeling (Robin & Scrucca, 2023).

Installation

You can install the released version of mclustAddons from CRAN using:

install.packages("mclustAddons")

Usage

For an introduction to the main functions and several examples see the vignette A quick tour of mclustAddons, which is available as

vignette("mclustAddons")

The vignette is also available in the Vignette section on the navigation bar on top of the package’s web page.
