ON D-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS [PDF]

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2015
The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.

D-optimal and nearly D-optimal exact designs for binary response on the ball

open access: yesStatistical Papers, 2023
AbstractIn this paper the results of Radloff and Schwabe (Stat Papers 60:165–177, 2019) will be extended for a special class of symmetrical intensity functions. This includes binary response models with logit and probit link. To evaluate the position and the weights of the two non-degenerated orbits on thek-dimensional ball usually a system of three ...

D-optimal experimental designs for linear multiple regression under heteroscedastic observations

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
The problem of construction of «continuous» (number of observations is not fixed) and «exact» (number of observations is fixed) D-optimal experimental designs for linear multiple regression in the case when variance of errors of observations depends on ...

Maximin optimal designs for a compartmental model [PDF]

open access: yes, 2004
For an important example from the class of compartmental models we determine optimal designs, which are robust against misspecifications of the unknown model parameters.

D-Optimal Design for Network A/B Testing [PDF]

open access: yesJournal of Statistical Theory and Practice, 2019
A/B testing refers to the statistical procedure of conducting an experiment to compare two treatments, A and B, applied to different testing subjects. It is widely used by technology companies such as Facebook, LinkedIn, and Netflix, to compare different algorithms, web-designs, and other online products and services.

Statistical Design of Experiments: An introductory case study for polymer composites manufacturing applications [PDF]

open access: yesMATEC Web of Conferences, 2021
Statistical design of experiments (DoE) aims to develop a near efficient design while minimising the number of experiments required. This is an optimal approach especially when there is a need to investigate multiple variables.

A combinatorial procedure for constructing D-optimal exact designs

open access: yesStatistica, 2013
The basic problem considered in this paper may be stated as follows: find an N-point exact design measure which maximizes the determinant of the information matrix of a given response function.

Development of a Solid Formulation Containing a Microemulsion of a Novel Artemisia Extract with Nematocidal Activity for Oral Administration

open access: yesPharmaceutics, 2020
Background: Intestinal nematode infections are usually treated with benzimidazole drugs, but the emergence of resistance to these drugs has led to an increasing demand of new anthelmintic strategies.
