D-optimal designs for Poisson regression models [PDF]

, 2008
We consider the problem of finding an optimal design under a Poisson regression model with a log link, any number of independent variables and an additive linear predictor.

Optimal Design for Estimating Parameters of the 4-Parameter Hill Model

Dose-Response, 2003
Many drug concentration-effect relationships are described by nonlinear sigmoid models. The 4-parameter Hill model, which belongs to this class, is commonly used. An experimental design is essential to accurately estimate the parameters of the model.

Dependence of Polypropylene Yarn Mechanical Properties on Manufacturing Parameters

Medžiagotyra, 2014
Polypropylene (PP) multifilament structure is a valuable way to prepare yarns for medical application. In this study iPP multifilament yarns were prepared from iPP granules Moplen 462R by melt spinning technique COLLIN® CMF-100.

Construction of symmetric paired choice experiments: minimising runs and maximising efficiency

Humanities & Social Sciences Communications, 2023
Discrete choice experiments (DCEs) are popular in various fields such as health resources, marketing, transport, economics, and many others for identifying the factors that influence an individual’s choice behaviour.

Exact Optimal Designs of Experiments for Factorial Models via Mixed-Integer Semidefinite Programming

Mathematics, 2023
The systematic design of exact optimal designs of experiments is typically challenging, as it results in nonconvex optimization problems. The literature on the computation of model-based exact optimal designs of experiments via mathematical programming ...

Selected Remarks on Highly D‑efficient Spring Balance Weighing Designs

Acta Universitatis Lodziensis. Folia Oeconomica, 2021
Here, we consider a new construction method of determining highly D-efficient spring balance weighing designs in classes in which a D-optimal design does not exist.

Selecting baseline designs using a minimum aberration criterion when some two-factor interactions are important

Statistical Theory and Related Fields, 2021
This article considers the problem of selecting two-level designs under the baseline parameterisation when some two-factor interactions are important.

D-Optimal Designs for Binary and Weighted Linear Regression Models: One Design Variable

Mathematics, 2023
D-optimality is a well-known concept in experimental design that seeks to select an optimal set of design points to estimate the unknown parameters of a statistical model with a minimum variance.

Construction of D-optimal saturated designs for main effects and F1-second-order interactions in the presence of a free factor

Statistical Theory and Related Fields
The allocation of resources in a [Formula: see text]-factorial experiment is crucial when the experimental resources are limited. In practice, when resources are limited, it is common for investigators to use all the information at their disposal to ...
