name: probable version: 0.1.3 synopsis: Easy and reasonably efficient probabilistic programming and random generation description: Easy and reasonably efficient probabilistic programming and random generation . This library gives a common language to speak about probability distributions and random generation, by wrapping both, when necessary, in a 'RandT' monad defined in @Math.Probable.Random@. This module also provides a lot of useful little combinators for easily describing how random values for your types should be generated. . In @Math.Probable.Distribution@, you'll find functions for generating random values that follow any distribution supported by . . In @Math.Probable.Distribution.Finite@, you'll find an adaptation of Eric Kidd's work on probability monads (from ). . You may want to check the examples bundled with this package, viewable online at . One of these examples is simple enough to be worth reproducing here. . > module Main where > > import Control.Applicative > import Control.Monad > import Math.Probable > > import qualified Data.Vector.Unboxed as VU > > data Person = Person Int -- ^ age > Double -- ^ weight (kgs) > Double -- ^ salary (e.g euros) > deriving (Eq, Show) > > person :: RandT IO Person > person = > Person <$> uniformIn (1, 100) > <*> uniformIn (2, 130) > <*> uniformIn (500, 10000) > > randomPersons :: Int -> IO [Person] > randomPersons n = mwc $ listOf n person > > randomDoubles :: Int -> IO (VU.Vector Double) > randomDoubles n = mwc $ vectorOf n double > > main :: IO () > main = do > randomPersons 10 >>= mapM_ print > randomDoubles 10 >>= VU.mapM_ print .
