RSS下Pareto分布中刻度参数的Fisher信息量

Fisher Information Amount of the Scale Parameter from Pareto Distribution Based on Ranked Set Sampling

研究了排序集抽样(RSS)下Pareto分布中刻度参数的Fisher信息量.为了突出RSS的优越性,将这个Fisher信息量与简单随机抽样(SRS)下刻度参数的Fisher信息量进行数值比较.数值结果表明,RSS下刻度参数的Fisher信息量多于SRS下的Fisher信息量.

The Fisher information amount of the scale parameter from Pareto distribution based on ranked set sampling （RSS） is studied. In order to give more insight into the performance of RSS compared with simple random sampling （SRS）, the Fisher information amount based on RSS is compared with that based on SRS. The numerical results show that the RSS--based scale parameter carries more Fisher in- formation than SRS--based ones.
