Abstract : A technique is developed for estimating the scale parameter of a Gamma distribution with known shape parameter using m order statistics. Basic properties of the Gamma distribution and certain theoretical concepts of order statistics are presented. A linear unbiased minimum variance estimate can be computed by applying tabulated multiplying factors to the first m ordered observations. Multiplying factors which yield oneorderstatistic estimates are also tabled. Two efficiencies for the oneorderstatistic estimators are given: the first is based on the morderstatistic estimator and the second is based on the maximum likelihood estimator. Table ranges include shape parameters alpha = 1(1)3 for sample sizes n = 1(1)20 and alpha = 4(1)6 for n = 1(1)15. (Author)
