%description
A variational Bayesian finite mixture model for the clustering of
categorical data, and can implement variable selection and semi-supervised
outcome guiding if desired. Incorporates an option to perform model
averaging over multiple initialisations to reduce the effects of local
optima and improve the automatic estimation of the true number of
clusters. For further details, see the paper by Rao and Kirk (2024)
<doi:10.48550/arXiv.2406.16227>.
