The distribution function of a statistic for testing the equality of scale parameters in two gamma populations. (English) Zbl 0691.62017

Summary: The exact distribution function of the ratio of two sums of gamma variates is derived. The result applies to ratios of quadratic forms and to a statistic used for testing equality of scale parameters in two gamma populations.
