ASA152
Hypergeometric Probabilities.

ASA152 is a C library which computes the "point" or "cumulative" probabilities associated with the hypergeometric probability distribution, by Richard Lund.

ASA152 is Applied Statistics Algorithm 152. Source code for many Applied Statistics Algorithms is available through STATLIB.
