Minimal non-circular balanced and strongly balanced repeated measurements designs.

Repeated measurements designs (RMD) are economical but with the use of these designs, residual or carry over effects may arise. To control these effects, balanced or strongly balanced RMDs should be used. In this article, using cyclic shifts, some infinite series are developed to obtain non-circular balanced and strongly balanced RMDs in periods of equal and unequal sizes. [ABSTRACT FROM AUTHOR]
