Robustness and Efficiency Problems of Some Randomization Procedures in Experimental Designs.
Abstract
A concept of model-robustness is defined in terms of the performance of the design in the presence of model violations. The robustness problem is discussed for several randomization procedures commonly used in experimental design situations. Among them the completely randomized design, the randomized block design and the randomized Latin square design are shown to be model-robust in their own settings. To compare different randomization procedures, a concept of efficiency is also defined. This concept, when applied to different designs, gives results which are consistent with the intuitive grounds on which the designs are suggested. (AUthor)
