Optimum Chemical Balance Weighing Designs Under Equal Correlations of Errors

1998
The paper deals with the problem of estimating the individual weights of objects using a chemical balance weighing design with equal correlations of errors in the usual linear model. A lower bound for the variance of each of the estimated weights resulting from this chemical balance weighing design is obtained and a necessary and sufficient condition ...

Robustness of Optimal Chemical Balance Weighing Designs for Estimation of Total Weight

Communications in Statistics - Theory and Methods, 2012
The subject of our study is the chemical balance weighing design in which the errors are correlated and have equal variances. A lower bound for the variance of estimated total weight is obtained and the necessary and sufficient conditions for the attainability of this lower bound are given.

A-optimal Chemical Balance Weighing Designs with Diagonal Covariance Matrix of Errors

2001
The paper deals with the problem of estimating the weights of objects using an A-optimal chemical balance weighing design with the covariance matrix of errors o2G, where G is an n x n known positive definite diagonal matrix. A lower bound of tr(X’G-1X)-1is obtained and a necessary and sufficient condition for this lower bound to be attained is given ...

Advances in Chemical and Spring Balance Weighing Designs: A systematic review

This paper deals with the review of the literature on Chemical and Spring Balance Weighing Designs. The Weighing problems were initially originated by Yates and after that Hotelling, who led to a precise formulation of the Weighing problem. Eventually, with the passage of time, this problem expanded to form a branch of Design of Experiment.
