%description
Implementations of the quantile slice sampler of Heiner et al. (2024+, in
preparation) as well as other popular slice samplers are provided. Helper
functions for specifying pseudo-target distributions are included, both
for diagnostics and for tuning the quantile slice sampler. Other
implemented methods include the generalized elliptical slice sampler of
Nishihara et al. (2014)<https://jmlr.org/papers/v15/nishihara14a.html},
latent slice sampler of Li and Walker
(2023)<doi:10.1016/j.csda.2022.107652>, and stepping-out slice sampler of
Neal (2003)<doi:10.1214/aos/1056562461>, and independence
Metropolis-Hastings sampler.
