【摘要】 研究了排序集抽样下样本参数的修正极大似然估计的性质,并以此估计为基础构造了样本参数的修正区间估计.研究表明:在相同的置信水平下,基于排序集抽样的样本参数的修正区间估计较传统的置信区间具有更高的精度.更多还原

【Abstract】 Studies the charactersof the modified maximum likelihood equation using ranked-set sampling for general parameters and construct modified confidence intervals of sample parameter, the research illustrates that under the same confidence level, the modified confidence interval for sample parameter based on ranked-set sampling is more accurate than traditional confidence interval.更多还原
