Comparison Between Dependent and Independent Ranked Set Sampling Designs for Parametric Estimation with Applications

On Maximum Likelihood Estimators of the Parameters of Three-Parameters Weibull Distribution Using Different Ranked Set Sampling Schemes

“…For example, [7] studied Weibull and Pareto distributions, [8] introduced the maximum likelihood estimation of the modified Weibull distribution parameters using extreme ranking set sampling, [9], [10] and [11].and a -stage RSS design uses +1 sample units from the target population to produce a sample of size after stages of ranking developed [12]. For more details, see [13], [14], [15] and [16], see more [17], [18] and [19].…”

“…Table 1and Table 2 lists the results of bias and MSE for different estimators, table (3) lists the efficiency results, and Figure (6)(7)(8)(9)(10)(11) shows the simulation results. The following conclusions can be observed from Table (1-2) 1) It is small biases in almost all cases…”
