Exact Confidence Intervals for a Variance Ratio in Mixed Linear Models
-
摘要: 本文利用信仰推断给出了求混合线性模型中方差比的置信区间的方法,结果表明所得区间估计具有不变性.另外,本文给出了两种求区间估计的近似方法.Abstract: In this paper, a new method is provided to construct exact confidence intervals for a variance ratio in the unbalanced mixed linear model via fiducial inference. It is shown that the resulted confidence intervals are invariant. Moreover, two approximate procedures are presented, which are very easy to compute.
