Estimators for the inverse powers of a normal mean

Christopher S. Withers, Saralees Nadarajah

    Research output: Contribution to journalArticlepeer-review


    Given a sample from a normal population unbiased estimators are obtained for positive powers of the mean and estimators of almost exponentially small bias are obtained for negative powers of the mean. Simulation studies show superior performance of these estimators versus known ones. © 2012 Elsevier B.V.
