| Summary : Speedy slice sampling
|
Description :
Speedy slice sampling.
This implementation of the slice sampling algorithm uses \'lens\' as a means to
operate over generic indexed traversable functors, so you can expect it to work
if your target function takes a list, vector, map, sequence, etc. as its
argument.
Additionally you can sample over anything that\'s an instance of both \'Num\' and
\'Variate\', which is useful in the case of discrete parameters.
Exports a \'mcmc\' function that prints a trace to stdout, a \'chain\' function for
collecting results in memory, and a \'slice\' transition operator that can be
used more generally.
