Some Construction Methods of A-Optimum Chemical Balance Weighing Designs

open access: yesJournal of Applied Mathematics and Physics, 2014
Some new construction methods of the optimum chemical balance weighing designs and pairwise efficiency and variance balanced designs are proposed, which are based on the incidence matrices of the known symmetric balanced incomplete block designs. Also the conditions under which the constructed chemical balance weighing designs become A-optimal are also

Some Construction Methods of Optimum Chemical Balance Weighing Designs III

open access: yesOpen Journal of Statistics, 2016
Methods of constructing the optimum chemical balance weighing designs from symmetric balanced incomplete block designs are proposed with illustration. As a by-product pairwise efficiency and variance balanced designs are also obtained.

Relations between optimum chemical balance weighing designs for v and v+1 objects [PDF]

open access: yesApplicationes Mathematicae, 1991
Summary: The incidence matrices of BIB designs for \(v\) treatments have been used to construct optimum chemical balance weighing designs for \(p=v\) or \(p=v+1\) objects. Conditions under which the existence of an optimum chemical balance weighing design for \(v\) objects implies the existence of an optimum chemical balance weighing design for \(v+1\)

Optimum chemical balance weighing design with diagonal matrix of errors based on balanced block designs

open access: yesActa et Commentationes Universitatis Tartuensis de Mathematica, 2004
The paper is studying the estimation problem of individual weights of objects using the chemical balance weighing design under the restriction on the number of times in which each object is weighed. Additionally, we assume that the errors are uncorrelated and they have different variances.

Some remarks about optimum chemical balance weighing design for p = v + 1 objects

open access: yesAdvances in Methodology and Statistics, 2009
The problem of the estimation of unknown weights of \(p = v + 1\) objects in the model of the chemical balance weighing design under the assumption that the measurement errors are uncorrelated and they have different variances is considered. The existence conditions determining the optimum design are presented.

Optimum Chemical Balance Weighing Design under Certain Condition

open access: yes, 2009
2000 Mathematics Subject Classification: 62K05, 05B05. The problem of estimation of unknown weights of p objects is considered. The experiment is carried out according to the standard Gauss-Markoff model of the chemical balance weighing design. Existence conditions of the optimum design are given.
