Abstract
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.
