Ds. Bhoj et M. Ahsanullah, ESTIMATION OF PARAMETERS OF THE GENERALIZED GEOMETRIC DISTRIBUTION USING RANKED SET SAMPLING, Biometrics, 52(2), 1996, pp. 685-694
The estimates of the parameters of the generalized geometric distribut
ion are obtained by using ranked set sampling procedure. These estimat
es are compared with the ordered least squares estimates given by Down
ton (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 pre
cision of our estimator for the population mean is higher than the usu
al estimator based on ranked set sampling.
