Documentation

module Control.Monad.Distribution.Base

type DDist = MVT Prob []

A discrete, finite probability distribution implemented using double-precision floating-point numbers.

ddist :: DDist a -> DDist a

Force a value to be interpreted as having type DDist.

type BDDist = MaybeT DDist

A version of BDDist with support for Bayes' theorem.

bddist :: BDDist a -> Maybe (DDist a)

Force a value to be interpreted as having type BDDist, and apply Bayes' rule. Returns Nothing if no possible combination of events will satisfy the guard conditions specified in BDDist.
