Abstract

In this work we have considered the problem of estimation of the location parameter of some distributions using extreme ranked set sampling (ERSS) with known coefficient of variation. We have discussed the general theory of estimation of the location parameter of a location-scale family of distributions, when the scale parameter is proportional to the location parameter using ERSS. Also we have estimated the best linear unbiased estimator (BLUE) of the mean of the normal distribution, logistic distribution and double exponential distributions with known coefficient of variation d using ERSS for some specific values of the sample size n.
