Open Source Ecosystems

This is a probability library inspired by Martin Erwig's and Steve Kollmansberger's "Probabilistic Functional Programming"[1], but with many additions and an underlying structure factored into monad transformers.

You will need MaybeT and MonadRandom from HackageDB:

http://hackage.haskell.org/packages/archive/pkg-list.html

...or from Darcs:

http://code.haskell.org/maybet/ http://code.haskell.org/monadrandom/

To install, type:

runhaskell Setup.hs configure runhaskell Setup.hs build runhaskell Setup.hs install

To build documentation, make sure Haddock is installed, and type:

runhaskell Setup.hs haddock

This library is highly experimental, and the APIs may change without notice.

The actual implementations of the probability monads currently appear in examples/Probability.hs. These will eventually be moved into the main library.
