%description
Estimate Bayesian nested mixture models via Markov Chain Monte Carlo
methods. Specifically, the package implements the common atoms model
(Denti et al., 2023), and hybrid finite-infinite models. All models use
Gaussian mixtures with a normal-inverse-gamma prior distribution on the
parameters. Additional functions are provided to help analyzing the
results of the fitting procedure. References: Denti, Camerlenghi,
