Approximate Percentiles For Ratios Of F-variates

Abstract

The need for percentiles of ratios of independent F-variates arises in many types of appliestions. Some tabulated values are available mostly for equal or nearly equal degrees-of-freedom cases, but it is not possible to provide comprehensive tables for the numerous combinations of possible degrees-of-freedom and probability levels. A simple approximation for the percentiles based on the Cornish-Fisher expansion technique is provided which is adequate for larger degrees-of-freedom and a more complicated approximation is provided which is suitable for all cases. The accuracy of the approximation is shown over a wide range of typical cases. © 1982, Taylor & Francis Group, LLC. All rights reserved.
