%description
Bayesian density estimates for univariate continuous random samples are
provided using the Bayesian inference engine paradigm. The engine options
are: Hamiltonian Monte Carlo, the no U-turn sampler, semiparametric mean
field variational Bayes and slice sampling. The methodology is described
in Wand and Yu (2020) <arXiv:2009.06182>.
