%description
Provides Bayesian inference for finite and infinite mixture models using
Markov chain Monte Carlo (MCMC) methods. Supports Gaussian, multivariate
Gaussian, Poisson, Binomial, and multivariate Bernoulli mixture kernels
with different covariance structures and flexible prior specifications.
Provides tools for data generation, posterior density evaluation,
clustering and similarity analysis, and advanced MCMC sampling strategies,
including reversible and non-reversible samplers: Ascolani et al. (2026)
