An R package implementing Gaussian Mixture Modelling for Model-Based Clustering, Classification, and Density Estimation.

Gaussian finite mixture models fitted via EM algorithm for model-based clustering, classification, and density estimation, including Bayesian regularization, dimension reduction for visualisation, and resampling-based inference.

Installation

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

install.packages("mclust")

Usage

Usage of the main functions and several examples are included in the papers shown in the references section below.

For an intro see the vignette A quick tour of mclust, which is available as

vignette("mclust")

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