%description
An efficient tool for fitting nested mixture models based on a shared set
of atoms via Markov Chain Monte Carlo and variational inference
algorithms. Specifically, the package implements the common atoms model
(Denti et al., 2023), its finite version (similar to D'Angelo et al.,
2023), and a hybrid finite-infinite model (D'Angelo and Denti, 2024). All
models implement univariate nested mixtures with Gaussian kernels equipped
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)
