# The random-fu package

Random number generation based on modeling random
variables in two complementary ways: first, by the
parameters of standard mathematical distributions and,
second, by an abstract type (`RVar`) which can be
composed and manipulated monadically and sampled in
either monadic or "pure" styles.
The primary purpose of this library is to support
defining and sampling a wide variety of high quality
random variables. Quality is prioritized over speed,
but performance is an important goal too.
In my testing, I have found it capable of speed
comparable to other Haskell libraries, but still
a fair bit slower than straight C implementations of
the same algorithms.
Warning to anyone upgrading from "< 0.1": `Discrete`
has been renamed `Categorical`, the entropy source
classes have been redesigned, and many things are no
longer exported from the root module `Data.Random`
(In particular, DevRandom - this is not available on
windows, so it will likely move to its own package
eventually so that client code dependencies on it will
be made explicit).
Support for `base` packages earlier than version 4
(and thus GHC releases earlier than 6.10) has been
dropped, as too many of this package's dependencies do
not support older versions.
The `Data.Random` module itself should now have a
relatively stable interface, but the other modules
are still subject to change. Specifically, I am
considering hiding data constructors for most or all
of the distributions.
