Notes on D‑optimal Spring Balance Weighing Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2018
Spring balance weighing design is a model of an experiment in which the result can be presented as a linear combination of unknown measurements of objects with factors of this combination equalling zero or one. In this paper, we assume that the variances

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

open access: yesRevstat 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.

Multiplication Algorithms for Approximate Optimal Distributions with Cost Constraints

open access: yesMathematics, 2023
In this paper, we study the D- and A-optimal assignment problems for regression models with experimental cost constraints. To solve these two problems, we propose two multiplicative algorithms for obtaining optimal designs and establishing extended D ...
