The properties about large samples of empirical likelihood for the differences of two m dependent samples mean are discussed in this paper ,which proves that the empirical Euclidean likelihood ratio statistic is asymptotically χ 2,and confidence interval for mean differences is given.
该文讨论了两m相依样本均值差异的经验似然的大样本性质,证明了经验似然比统计量依分布收敛于χ2随机变量,由此给出均值差异的经验似然置信区间。
补充资料：Poh值
poh值是表示溶液中oh-离子浓度的一种方法，poh代表氢氧根离子的浓度的负对数，即：poh=-1g〔oh-〕。根据poh值可以计算出溶液中氢氧根离子的浓度。
