Documentation

class Sampleable d m t where Source

A typeclass allowing Distributions and RVars to be sampled. Both may also be sampled via runRVar or runRVarT, but I find it psychologically pleasing to be able to sample both using this function. Methods sampleFrom :: RandomSource m s => s -> d t -> m t Source Directly sample from a distribution or random variable, using the given source of entropy. Instances Lift m n => Sampleable (RVarT m) n t

sample :: (Sampleable d m t, MonadRandom m) => d t -> m t Source

Sample a distribution using the default source of entropy for the monad in which the sampling occurs.
