Some Contributions to the Theory of Multistage Youden Design

Abstract

It is shown that complete sets of $(\nu - 1)/2$ by $\nu$ and $(\nu + 1)/2$ by $\nu$ multistage balanced Youden designs of type I and II can be constructed if $\nu$, the number of treatments, is a prime power of the form $4\lambda + 3$. It is also proved that the existence of a difference set with certain properties implies the existence of a 2-stage balanced Youden design. The usefulness of this latter result is demonstrated for those experiments where the number of treatments is not a prime power.
