Abstract

In this article we have developed a method of estimating the common location parameter μ of several distributions having further a common scale parameter which is proportional to μ using ranked set sampling (RSS). For illustration purpose we estimate the common mean of normal, and logistic distributions with known coefficient of variation using RSS. Efficiency comparison of the proposed estimator using RSS of independent but not identically distributed (inid) random variables with that of using order statistics of inid random variables is also made.
