runif_on_sphere

runif_in_sphere

Uniform sampling on a sphere or in a sphere, in arbitrary
dimension.

internal

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.
