%description
Implements the truncated harmonic mean estimator (THAMES) of the
reciprocal marginal likelihood for uni- and multivariate mixture models
using posterior samples and unnormalized log posterior values via
reciprocal importance sampling. Metodiev, Irons, Perrot-Dockès, Latouche &
Raftery (2025) <doi:10.48550/arXiv.2504.21812>.
