Abstract:
|
Experiments in pharmaceutical and health sciences often involve comparisons of test treatments to more than one control. However, the controls may not always be of equal importance. The question of allocating resources to the treatments and the controls depends upon the relative importance of the controls. Here we discuss this allocation from a weighted MV optimality and A optimality framework. We provide approximate as well as analytical results. One-way-layout and Block Design lay-out are studied.
