The Ratio of Variances in a Variance Components Model [PDF]
1. The general incomplete block variance components model. Suppose that yij for i = 1, * ,u, and j = 1, * ,b are independent and normal for given ti I., I tu with means E(yij I t) = nij(ti + bj) and v-ariance a2.

On quadratic estimates of variance components
In this paper quadratic estimates of variance components are considered. For the general balanced nested classification with no specific distributions assumed, it is shown that the quadratic estimate which is unbiased and which has minimum variance is given by the analysis of variance method of estimating the variance components.

Minimum variance quadratic unbiased estimation of variance components
AbstractThe variance of a quadratic function of the random variables in a linear model is minimized to obtain locally best unbiased estimators (MIVQUE) of variance components. Condition for such estimators to be independent of the kurtosis of the variables is given.
