Usefulness of a Cyclic Designs for Two-Factor Experiments

Cyclic designs are incomplete block designs based on cyclic development of an initial block. Their flexibility, ease in conduct of the experiment, is worthy of attention even though their analysis has less ease of computation than the completely balanced or partially balanced incomplete block designs with two associated classes. In this paper, cyclic designs for two-factor experiments are considered. It is shown that cyclic designs for two-factor experiments can be easily obtained and two main effects and interaction effect are orthogonal each other. The efficiencies of these designs are also provided.
