正态总体均值方差的经验似然比置信区间估计

Empirical Likelihood Ratio Confidence Interval Estimation for Normal Population Parameters

经验似然近年来取得了很大的进展,文章针对正态总体在均值未知情况下,讨论了总体均值方差的联合经验似然估计,又利用均值的无偏估计量X代替均值的情况下,给出了其方差的经验似然置信区间.

Great advancement have been achieved in Empirical Likelihood method in recent years.This paper discusses the joint maximum likelihood estimation of general mean-variance accoding to the unknowing of normal population mean,as well as give the confidence interval of empirical likelihood about variance in the situation of unbiased estimators inteading of mean.
