摘要
The estimates of the parameters of the generalized geometric distribution are obtained by using ranked set sampling procedure. These estimates are compared with the ordered least squares estimates given by Downton (1954, Annals of Mathematical Statistics 25, 303-316). It is shown that the relative precisions of our estimators are higher than those of the ordered least squares estimators. Furthermore, the relative precision of our estimator for the population mean is higher than the usual estimator based on ranked set sampling.
