Documentation
class Sampleable d m t whereSource
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 tSource
Directly sample from a distribution or random variable, using the given source of entropy.
Instances
| Distribution d t => Sampleable d m t | |
| Lift m n => Sampleable (RVarT m) n t |
sample :: (Sampleable d m t, MonadRandom m) => d t -> m tSource
Sample a distribution using the default source of entropy for the monad in which the sampling occurs.
