#' Addons for the **mclust** package
#' 
#' @description
#' An R package extending the functionality of the **mclust** package 
#' (Scrucca et al. 2916, 2023) for Gaussian finite mixture modeling by 
#' including: 
#' 
#' * density estimation for data with bounded support (Scrucca, 2019) 
#' * modal clustering using MEM algorithm for Gaussian mixtures (Scrucca, 2021)
#' * entropy estimation via Gaussian mixture modeling (Robin & Scrucca, 2023)
#' 
#' For a quick introduction to *mclustAddons* see the vignette
#' \href{../doc/mclustAddons.html}{A quick tour of mclustAddons}.
#' 
#' @seealso 
#' [densityMclustBounded()] for density estimation of bounded data; 
#' [MclustMEM()] for modal clustering;
#' [EntropyGMM()] for entropy estimation.
