摘要
通过讨论两总体方差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,由此给出方差差异的经验似然置信区间。
We discusses the properties about large samples of empirical likelihood for the differences of two populations variance in this paper, and also proves that the empirical Euclidean likelihood ratio statistic is asymptotically χ^2 ,Then, confidence regions for variance differences are given.
