Notes on the Regular E-Optimal Spring Balance Weighing Designs with Correlated Errors

Abstract

The paper deals with the estimation problem of individual weights of objects in Eoptimal spring balance weighing design. It is assumed that errors are equal correlated. The topic is focused on the determining the maximal eigenvalue of the inverse of information matrix of estimators. The constructing methods of the E-optimal spring balance weighing design based on the incidence matrices of balanced and partially balanced incomplete block designs are given.
