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 ...

Embedding cocylic D-optimal designs in cocylic Hadamard matrices [PDF]

open access: yes, 2012
A method for embedding cocyclic submatrices with “large” determinants of orders 2t in certain cocyclic Hadamard matrices of orders 4t is described (t an odd integer).

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

open access: yesStatistical 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 ...

Construction D-optimal designs of experiments for linear multiple regression with heteroscedastic observations

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In article the problem of construction exact D-optimal designs of experiments for linear multiple regression in a case when variance of errors of observations depend on a point in which is made is investigated.

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.

D-optimal saturated designs for main effects and interactions in 2k-factorial experiments

open access: yesStatistical Theory and Related Fields
In a [Formula: see text]-factorial experiment with limited resources, when practitioners can identify the non-negligible effects and interactions beforehand, it is common to run an experiment with a saturated design that ensures the unbiased estimation ...

Delineamentos experimentais eficientes para estudos de cinética química

open access: yesQuímica Nova, 2014
In this paper we show how to obtain efficient designs of experiments for fitting Michaelis-Menten and Hill equations useful in chemical studies. The search of exact D-optimal designs by using local and pseudo-Bayesian approaches is considered.

A Highly D‑efficient Spring Balance Weighing Design for an Even Number of Objects

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2019
The problem of determining unknown measurements of objects in the model of spring balance weighing designs is presented. These designs are considered under the assumption that experimental errors are uncorrelated and that they have the same variances ...
