ABSTRACT
The estimators of the parameters of Laplace distribution are obtained by using (i) ranked set sampling (RSS) proposed by Mclntyre (1952), (ii) modified ranked set sampling (MRSS), and (iii) new ranked set sampling (NRSS) proposed by Bhoj (1997c). The coefficients to compute the estimators by using these procedures are reported. These estimators are compared with the ordered least squares estimators given by Govindarajulu (1966), and among themselves. It is demonstrated that the relative precisions of the estimators based on NRSS are higher than those based on the least squares method and the other two ranked set sampling procedures.
