-- | Hypergeometric functions
--   
--   Haskell implementation of hypergeometric functions and associated
--   statistical and special functions, viz. erf, normal cdf, incomplete
--   beta, F-distribution cdf, <math>-distribution cdf, t-distrubtion
--   cdf. Also includes Lanczos' approximation of the gamma function.
