Title: Search for optimality in the estimation of variance components
Authors: Subir Ghosh - University of California (United States) [presenting]
Abstract: The optimal estimators of variance components with closed form expressions are often difficult or impossible to obtain. In such situations, the search for estimators near to the optimal estimators are presented satisfying the condition of unbiasedness. In addition, the estimators have exact closed form expressions. When the closed form expressions are unavailable for the optimum estimators of variance components, the proposed near optimal estimators are obtained as approximation to the optimal estimators. Illustrative examples are presented.
