Orthogonal factorial and fractional factorial designs are very popular in many experimental studies, particularly in industrial screening experiments. When an experimenter is able to specify the set of nonnegligible factorial effects, it is sometimes possible to obtain an orthogonal design belonging

โฆ Synopsis
Orthogonal designs are very popular in many experimental studies because of their optimality properties, ease of analysis, and ease of interpretation. In this paper, we prove a necessary and su cient condition for a parallel-ats design to be orthogonal for estimating the factorial e ects of hierarchical models for general
, where s1; s2; : : : ; sg are assumed to be distinct primes. Some examples are given to illustrate the results.

This paper revisits the concepts of orthogonal block structure and orthogonal design in mixed linear models. The primary tool used in investigating these concepts is that of a commutative quadratic subspace. The idea of an error orthogonal design is introduced. These designs are less restrictive tha
In this paper, orthogonal designs of parallel ats type are generated for 3 m and mixed 2 n ร 3 m factorial experiments, where factor e ects include the general mean, main e ects, and certain classes of two-factor interactions.
