REGULAR D-OPTIMAL SPRING BALANCE WEIGHING DESIGNS: CONSTRUCTION [PDF]

Acta Universitatis Lodziensis. Folia Oeconomica, 2014
Spring balance weighing design there is the model of experiment in that the result of experiment we can present as linear combination of unknown measurements of objects with factors of this combination equal to zero or one.

Notes on Selected Optimal Weighing Designs

Acta Universitatis Lodziensis. Folia Oeconomica, 2021
In this paper, some problems related to the construction of highly D‑efficient spring balance weighing designs are presented. We give some conditions determining the relations between the parameters of such designs and construction examples.

Highly D-Efficient Weighing Designs for an Even Number of Objects

Revstat Statistical Journal, 2018
In this paper we formulate how to add a = 1, 2, 3 runs to a near D-optimal weighing design to get a highly D-efficient weighing design when the number of objects p is even.

Regular A-optimal spring balance weighing designs with correlated errors

Hacettepe Journal of Mathematics and Statistics, 2014
The problems linked with an E-optimal spring balance weighing design with correlated errors are discussed. The topic is focus on the determining the maximal eigenvalue of the inverse of the information matrix of estimators. The constructing method of the E-optimal design, based on the incidence matrices of balanced incomplete block designs, is ...

Catalogue of selected experimental plans

Biometrical Letters, 2021
Summary There are many works in the literature on the construction of experimental plans based on weighing designs. Hence, it is useful to compile a catalogue of experimental designs with specific properties.
