Inferential Procedures On The Shape Parameter Of A Gamma Distribution From Censored Data
Various techniques are used to find the first two moments of the statistic T = log (Ar/Gr), where Arand Grare, respectively, the Winsorized arithmetic and geometric means based on censored data from a gamma distribution. A two-moment chi-squared approximation is then derived for T and used for testing hypotheses and setting confidence bounds on the shape parameter of a gamma distribution. Power comparisons are made between optimum tests and the corresponding tests based on T. © 1979, Taylor & Francis Group, LLC.
