%description
Clustering via parsimonious Gaussian Mixtures of Experts using the
MoEClust models introduced by Murphy and Murphy (2020)
<doi:10.1007/s11634-019-00373-8>. This package fits finite Gaussian
mixture models with a formula interface for supplying gating and/or expert
network covariates using a range of parsimonious covariance
parameterisations from the GPCM family via the EM/CEM algorithm.
Visualisation of the results of such models using generalised pairs plots
and the inclusion of an additional noise component is also facilitated. A
greedy forward stepwise search algorithm is provided for identifying the
optimal model in terms of the number of components, the GPCM covariance
parameterisation, and the subsets of gating/expert network covariates.
