Quasi-orthogonal Arrays and Optimal Fractional Factorial Plans
نویسندگان
چکیده
Generalizing orthogonal arrays, a new class of arrays called quasiorthogonal arrays, are introduced and it is shown that fractional factorial plans represented by these arrays are universally optimal under a wide class of models. Some methods of construction of quasi-orthogonal arrays are also described.

Cluster Orthogonal Arrays and Optimal Fractional Factorial Designs
A generalization of orthogonal arrays, namely cluster orthogonal arrays (CLOA), is introduced and some properties and construction methods are studied. The universal optimality of the fractional factorial designs represented by cluster orthogonal arrays is proved.
متن کاملOptimal Semifoldover Plans for Two-Level Orthogonal Designs
Foldover is a widely used procedure for selecting follow-up experimental runs. As foldover designs require twice as many runs as the initial design, they can be inefficient if the number of effects to be dealiased is smaller than the size of the original experiment. Semifolding refers to adding half of a foldover fraction and is a technique that has been investigated in recent literature for re...
متن کاملOrthogonal Arrays
(say) is called symmetric, otherwise, the array is said to be asymmetric. Several methods of construction of symmetric as well as asymmetric OAs are available in the literature. Some important methods will be discussed here. One of the principal applications of the OAs is in the selection of level combinations for fractional factorial experiments. An OA of strength t is equivalent to an orthogo...
متن کاملTaguchi’s Orthogonal Arrays Are Classical Designs of Experiments
Taguchi's catalog of orthogonal arrays is based on the mathematical theory of factorial designs and difference sets developed by R. C. Bose and his associates. These arrays evolved as extensions of factorial designs and latin squares. This paper (1) describes the structure and constructions of Taguchi's orthogonal arrays, (2) illustrates their fractional factorial nature, and (3) points out tha...
متن کاملInter-effect Orthogonality and Optimality in Hierarchical Models
The study of optimal fractional factorial plans has received considerable attention over the last two decades. The universal optimality of plans based on orthogonal arrays was shown by Cheng (1980) and Mukerjee (1982). Various extensions of this result have also been reported in the literature; see Mukerjee (1995) for a brief review. Most of these results relate to situations where all factoria...
