摘要：

An algorithm is given for evaluating the incomplete beta function ratio I(x)(a, b) and its complement 1 - I(x)(a, b). A new continued fraction and a new asymptotic series are used with classical results. A transportable Fortran subroutine based on this algorithm is currently in use. It is accurate to 14 significant digits when precision is not restricted by inherent error.
