| 摘 要： | 本文首先给出了随机双向分类模型中方差分量基于由方差分析产生的平方和的区间估计．然后以此为基础进行了改进，推导出了同时依赖于均值与平方和的区间估计．二者的区间长度相同，但后者有较高的置信度．

| Abstract: | In this paper, we construct firstly the interval estimates of variance components in the two-way model ,depending on corresponding sums of squares from the analysis of variance. It has been shown in this paper that interval estimates of variance compenents relies on not only sums of squares but also the population mean in the basis of the above construction. The both have the same length but the latter has a bigger confidence. |
