摘要
针对K元排序集抽样的一个特例极端排序集抽样2(ERSS2)进行符号秩检验,给出该抽样方法的精确和大样本渐近分布,通过分析计算ERSS2与简单随机抽样SRS的Pitman渐近相对效率,得出在排序花费不可忽略时,对小样本,在检验中位数时,ERSS2比RSS更有效,然而对于大样本的情形,ERSS2只优于SRS.
The sign ranked test is proceeded against a special ease of k - tuple ranked set samples, extreme ranked set sampling 2 （ERSS2）. The asymptotic distribution of big samples is investigated. Thought the comparison of Pitman asymptotic relative efficiency of ERSS2 versus SRS, it is concluded that when the ranking cost is not ignored, in the small sample case ERSS2 better than RSS for the median test, while in the big sample ease ERSS2 only better than SRS.
