| Abstract: | This paper concerns the problem of “improving” interval estimators of variance components in one-way random model. The traditional method of construction relies on the establishment of confidence intervals, depending on corresponding sums of squares, from the analysis of variance. It has been shown in the paper how information on the estimator for a population mean can be used to “improve” the estimation of variance components. |
