Optimal Designs for Direct Effects: The Case of Two Treatments and Five Periods

open access: yesMathematics, 2023
Cross-Over Designs or Repeated Measurements Designs are experimental designs in which treatments (e.g., medicines, fertilizers, diets) are applied to experimental units (usually humans) in different time periods.

M-estimator, and D-optimality model construction using orthogonal forward regression

open access: yes, 2005
This correspondence introduces a new orthogonal forward regression (OFR) model identification algorithm using D-optimality for model structure selection and is based on an M-estimators of parameter estimates.

Generating Improved Experimental Designs with Spatially and Genetically Correlated Observations Using Mixed Models

open access: yesAgronomy, 2018
The aim of this study was to generate and evaluate the efficiency of improved field experiments while simultaneously accounting for spatial correlations and different levels of genetic relatedness using a mixed models framework for orthogonal and non ...

Algorithms for the minimum spanning tree problem with resource allocation

open access: yesOperations Research Perspectives, 2016
We formulate the minimum spanning tree problem with resource allocation (MSTRA) in two ways, as discrete and continuous optimization problems (d-MSTRA/c-MSTRA), prove these to be NP-hard, and present algorithms to solve these problems to optimality.

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.

On the number of D-optimal designs

open access: yesJournal of Combinatorial Theory, Series A, 1994
The main result of the paper is the theorem: For \(n=18\), there are precisely three essentially different matrices with elements \(\pm 1\) having the maximum determinant. Only one of these is of the circulant type, but all are of the skew type. This means that there are three \(D\)-optimal designs for \(n=18\).

Recent advances in maximum-entropy sampling

open access: yesKuwait Journal of Science
In 2022, we published the book Maximum-Entropy Sampling: Algorithms and Application (Springer). Since then, there have been several notable advancements on this topic. In this manuscript, we survey some recent highlights.
