Significant Digit Computation of the Incomplete Beta Function Ratios
Armido R. Didonato, Jr Morris, H. Alfred · 1988
Abstract : An algorithm is given for evaluating the incomplete beta function ratio 1 sub x (a,b) and its complement 1-I sub x (a,b). Two new procedures are used with classical results. A listing of a transportable Fortran subroutine using this algorithm is given. The subroutine is accurate to 14 significant digits when the precision is not restricted by inherent error. Keywords: Computations.
