摘要:	In this paper, we propose the weighted moments estimators (WMEs) of the scale parameter of the exponential distribution based on a multiply type II censored sample. When compared to the approximate maximum likelihood estimator (AMLE) by Balakrishnan (1990) and the best linear unbiased estimator (BLUE) by Balasubramanian and Balakrishnan (1992) (or Upadhyay et al. (1996)) in terms of the simulated mean squared errors (MSEs) of AMLE and BLUE and exact MSEs of WMEs, we find that some of the WMEs are better than the AMLE and BLUE for given sample sizes and different censoring schemes. Further, we also obtain the best estimator among the WMEs, AMLE and BLUE.
