Mixture-of-Experts Wishart Models for Covariance Data // Methods for maximum likelihood and Bayesian estimation for the Wishart mixture model and the mixture-of-experts Wishart (MoE-Wishart) model. The package provides four inference algorithms for these models, each implemented using the expectationmaximization (EM) algorithm for maximum likelihood estimation and a fully Bayesian approach via Gibbs-within-MetropolisHastings sampling.
