On the E-optimality of complete block designs under a mixed interference model
چکیده انگلیسی
In experiments in which the response to a treatment can be affected by other treatments, the interference model with neighbor effects is usually used. It is known that circular neighbor balanced designs (CNBDs) are universally optimal under such a model if the neighbor effects are fixed (Druilhet, 1999) or random (Filipiak and Markiewicz, 2003, 2007). However, such designs cannot exist for every combination of design parameters. In the class of block designs with the same number of treatments as experimental units per block, a CNBD cannot exist if the number of blocks, b, is equal to p(t−1)±1, where p is a positive integer and t is the number of treatments. Filipiak et al. (2008) gave the structure of the left-neighboring matrix of E-optimal complete block designs with p=1 under the model with fixed neighbor effects. The purpose of this paper is to generalize E-optimality results for designs with p∈N assuming random neighbor effects.
