On Highly D-Efficient Designs with Nonnegatively Correlated Observations

open access: yesRevstat Statistical Journal, 2017
In the most difficult case where the number of observations n ≡ 3 (mod 4), high D-efficiency of certain chemical balance weighing designs under completely symmetric covariance matrix of errors is shown. It is also proved that D-optimal design may depend

Optimal designs for smoothing splines [PDF]

open access: yes
In the common nonparametric regression model we consider the problem of constructing optimal designs, if the unknown curve is estimated by a smoothing spline.

An Equivalence Theorem and A Sequential Algorithm for A-Optimal Experimental Designs on Manifolds

open access: yesAxioms
Selecting input data points in the context of high-dimensional, nonlinear, and complex data in Riemannian space is challenging. While optimal experimental design theory is well-established in Euclidean space, its extension to Riemannian manifolds remains

Robust D-Optimal Mixture Designs Under Manufacturing Tolerances via Multi-Objective NSGA-II

open access: yesMathematics
This study proposes a multi-objective optimization framework for generating statistically efficient and operationally robust designs in constrained mixture experiments with irregular experimental regions. In industrial settings, manufacturing variability

Maximin optimal designs for the compartmental model [PDF]

open access: yes
For the compartmental model we determine optimal designs, which are robust against misspecifications of the unknown model parameters. We propose a maximin approach based on D-efficiencies and provide designs that are optimal with respect to the ...

Optimal two-level conjoint designs for large numbers of attributes. [PDF]

open access: yes
In this paper, we propose a simple strategy to construct D-, A-, G- and V-optimal two-level multi-attribute designs for rating-based conjoint studies. Our approach combines orthogonal designs and balanced or partially balanced incomplete block designs ...

Locally D-optimal Designs for Exponential Regression [PDF]

open access: yes
We study locally D-optimal designs for some exponential models that are frequently used in the biological sciences. The model can be written as an algebraic sum of two or three exponential terms.

YÜKSELTİLMİŞ D-OPTİMAL DİZAYN YÖNTEMİ KULLANILARAK MÜHENDİSLİK DİZAYNLARINDA ETKİNLİĞİN GELİŞTİRİLMESİ: ‘SENTETİK JET’ DİZAYN OPTİMİZASYON ÇALIŞMASI

open access: yesHavacılık ve Uzay Teknolojileri Dergisi, 2007
The purpose of this study is to study the efficiency of several “design of experiments” (DOE) approaches used for the analysis and optimization of engineering designs.
