Abstract
In [Temme N.M., Special functions. An introduction to the classical functions of mathematical physics, A WileyInterscience Publication, John Wiley & Sons, Inc., New York, 1996, Section 11.3.3.1] a uniform asymptotic expansion for the incomplete beta function was derived. It was not obvious from those results that the expansion is actually an asymptotic expansion. We derive a remainder estimate that clearly shows that the result indeed has an asymptotic property, and we also give a recurrence relation for the coefficients.
Key words:
incomplete beta function; uniform asymptotic expansion.
