Comparing the means of several experimental groups is an old and well known
problem in the statistical literature which arises in many application areas. In the
past decades, a large body of literature about the design of experiments for treatment
comparisons has flourished. However, the attention has been almost exclusively devoted
to estimation precision, and not to optimal testing. This...
The probability distribution of the response variable is one of the necessary assumptions in the design of an experiment and the existence of uncertainty supposes a challenge for practitioners. The aim of this work is the analysis of four strategies to obtain robust optimal designs in order to face this uncertainty. The strategies compared in this paper are compound criteria, multi-stage...
One of the main criticisms to the optimal experimental design theory is that optimal designs tend to require too few points, frequently very extremal. In most of the models with one variable the number of different points reduces to the number of parameters to be estimated. Actually, an optimal design is used as a reference to measure how efficient are the designs used in practice. In this...
