Optimal experimental designs for treatment contrasts in heteroscedastic models with covariates
Samuel Rosa
In clinical trials, the response of a given subject often depends on the selected treatment as well as on some covariates. We study optimal approximate designs of experiments in th…

Removal of the points that do not support an E-optimal experimental design
Radoslav Harman, Samuel Rosa
We propose a method of removal of design points that cannot support any E-optimal experimental design of a linear regression model with uncorrelated observations. The proposed meth…

E- and R-optimality of block designs for treatment-control comparisons
Samuel Rosa
We study optimal block designs for comparing a set of test treatments with a control treatment. We provide the class of all E-optimal approximate block designs characterized by sim…
