Abstract

This paper concerns the distribution of the sum of k largest observations in a sample of m observations from a gamma distribution with n degrees of freedom. The density and cdf of the distribution are given as a sum of gamma density functions. If n is integer valued then the sum consists of a finite number of terms. The distribution of the sum arises in a problem of selecting variables in multiple regression analysis.
