%description
An efficient tool for fitting the nested common and shared atoms models
using variational Bayes approximate inference for fast computation.
Specifically, the package implements the common atoms model (Denti et al.,
2023), its finite version (D'Angelo et al., 2023), and a hybrid
finite-infinite model. All models use Gaussian mixtures with a
normal-inverse-gamma prior distribution on the parameters. Additional
functions are provided to help analyze the results of the fitting
procedure. References: Denti, Camerlenghi, Guindani, Mira (2023)
