This paper generalizes the estimator proposed by Searles (1964) and further studied by S RIVASTAVA (1980) and gives some expressions for the first two moments and an integral representation for the α th raw moment. The latter is found suitable for computational purposes. Some points in S RIVASTAVA'S (1980) paper are also clarified. Efficiencies of 3 estimators belonging to this class are analyzed with respect to the usual sample mean.
