%description
Performs Bayesian nonparametric density estimation using Martingale
posterior distributions including the Copula Resampling (CopRe) algorithm.
Also included are a Gibbs sampler for the marginal Gibbs-type mixture
model and an extension to include full uncertainty quantification via a
predictive sequence resampling (SeqRe) algorithm. The CopRe and SeqRe
samplers generate random nonparametric distributions as output, leading to
complete nonparametric inference on posterior summaries. Routines for
calculating arbitrary functionals from the sampled distributions are
included as well as an important algorithm for finding the number and
location of modes, which can then be used to estimate the clusters in the
data using, for example, k-means. Implements work developed in Moya B.,
