%description
Provides flexible Bayesian estimation of Infinite Mixtures of Infinite
Factor Analysers and related models, for nonparametrically clustering
high-dimensional data, introduced by Murphy et al. (2020)
<doi:10.1214/19-BA1179>. The IMIFA model conducts Bayesian nonparametric
model-based clustering with factor analytic covariance structures without
recourse to model selection criteria to choose the number of clusters or
cluster-specific latent factors, mostly via efficient Gibbs updates.
Model-specific diagnostic tools are also provided, as well as many options
for plotting results, conducting posterior inference on parameters of
interest, posterior predictive checking, and quantifying uncertainty.
