An R package extending the functionality of the mclust package (Scrucca et al. 2016) by including:

  • density estimation for data with bounded support using a transform-based approach to Gaussian mixture density estimation;
  • modal clustering using modal EM algorithm for Gaussian mixtures.

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.
