# random-fu: Random number generation

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.

Changes in 0.2.4.0: Added a Lift instance that resolves a common overlapping-instance issue in user code.

Changes in 0.2.3.1: Should now build on GHC 7.6

Changes in 0.2.3.0: Added stretched exponential distribution, contributed by Ben Gamari.

Changes in 0.2.2.0: Bug fixes in Data.Random.Distribution.Categorical.

Changes in 0.2.1.1: Changed some one-field data types to newtypes, updated types for GHC 7.4's removal of Eq and Show from the context of Num, and added RVarT versions of random variables in Data.Random.List
