ASA310 is a C++ library which computes the cumulative distribution function (CDF) of the noncentral Beta distribution.
ASA310 is Applied Statistics Algorithm 310. Source code for many Applied Statistics Algorithms is available through STATLIB.
Warning: I could not get this algorithm to perform properly until I had made a number of corrections.
Note that the printed text of the algorithm, and the online version distributed by APSTAT, omit a crucial initialization of the variable S to zero.
Moreover, there are two typographical errors introduced into the online version distributed by APSTAT; in both cases a multiplication symbol became a minus sign.
Finally, note that the authors of AS 310 invoke AS 226, but specifically recommend that the changes submitted by Frick NOT be included. The version of AS 226 distributed by APSTAT includes the Frick changes; the version of AS310 distributed by APSTAT includes this copy of AS 226, and hence the changes suggested by Frick.
