The research on orthogonal arrays

11 THE RESEARCH ON ORTHOGONAL ARRAYS (M. Sc. Thesis) Ashhan ALHAN GAZİ UNIVERSITY INSTITUTE OF SCIENCE AND TECHNOLOGY May 2001 ABSTRACT Orthogonal arrays are statistical method which the terminology comes from experimental design. In this study, it has been considered on problems of construction of orthogonal arrays. Further, it is analyzed by algebraically and geometrical properties. Hence, all references are researched and examples are given for understandable this of subject. Moreover, some important experimental designs are given. It used properties of orthogonal arrays for these arrays of construction. Finally, it is researched other experimental designs transition from existence of orthogonal arrays. Therefore, orthogonal arrays could have expanded to others experimental designs.
