I believe we should discuss what might be a copyright infringement issue with the two normal cdf algorithms.
NormalCDFPreciseAlgorithm cites a couple sources for its implementation: 1. R which is protected by GPL 2. TOMS 715 which is protected by ACM's CALGO license, http://www.acm.org/calgo/copyright.htm NormalCDFFastAlgorithm cites Applied Statistics as its source. AS is copyrighted by The Royal Statistical Society and the only thing I could find about its licensing is a little blurb at http://lib.stat.cmu.edu/apstat/ stating "The Royal Statistical Society holds the copyright to these routines, but has given its permission for their distribution provided that no fee is charged." I ask that everyone concerned to familiarize themselves with these two implementations and citations. Then, we should decide on a course of action regarding these two classes. Prior to that, some more investigation might be necessary for the RSS license terms as the above quoted, statement is a little open ended.
