A differential operator is defined and applied to the gamma density function. By formal mathematical manipulations, the resulting function is identified with the distribution function of the noncentral chi-square distribution. Several series expansions of a general nature result, and a table is presented comparing the effectiveness of seven series in evaluating this distribution function.
