Besides, the PCE and MLE exhibit a better performance than the other estimators for n = 100 and 200, respectively. Lastly, the figures given in Table 2 indicate that the MME outperforms the other estimators with the smallest deficiency when the sample sizes are 10,20 and 30. However, for n = 50, the MPWME is the best estimator. Additionally, the PCE and MLE again exhibit a good performance, respectively, when n = 100 and 200
