Chemical Balance Weighing Design with Different Variances of Errors

, 2005
The paper is studying the estimation problem of individual weights of objects using a chemical balance weighing design under the restriction on the number of times in which each object is weighed. We assume that errors are uncorrelated with different variances.

Optimum chemical balance weighing designs under the restriction on weighings [PDF]

Discussiones Mathematicae Probability and Statistics, 2001
The problem addressed here is concerned with estimating individual weights of objects by using a chemical balance weighing design under the constraint on the number in which each object is weighed. The model for a chemical balance design is \(y(n\times 1)= x(n\times p)w(p\times 1)+ e(n\times 1)\), when \(y\) is a vector of observations, \(x\) is the ...

Use of balanced bipartite weighing designs as chemical balance designs

Communications in Statistics - Theory and Methods, 1982
This paper deals with the use of balanced bipartite weighing designs as chemical balance designs when there Is a restriction on the number of objects that can be placed on either pan..The variance of each estimated weight and the covarlance of each pair of estimated weights are worked out.The use of additional weighing when the design matrix is ...

A relation between BIB designs and chemical balance weighing designs

Statistics & Probability Letters, 1987
The paper gives a certain new construction method for optimum chemical balance weighing designs. It utilizes a relation between the incidence matrices of a set of BIB designs and the design matrix of a chemical balance weighing design.
