Title: Column-orthogonal strong orthogonal arrays
Authors: Min-Qian Liu - Nankai University (China) [presenting]
Abstract: Strong orthogonal arrays were recently introduced as a new class of space-filling designs for computer experiments due to their better stratifications than orthogonal arrays. To further improve the space-filling properties in low dimensions while possessing the column orthogonality, column-orthogonal strong orthogonal arrays of strength two stars and three are proposed. Construction methods and characterizations of such designs are provided. The resulting strong orthogonal arrays, with the number of levels being increased, have their space-filling properties in one and two dimensions being strengthened. They can accommodate comparable or even larger numbers of factors than those in the existing literature, enjoy flexible run sizes, and possess column orthogonality. The construction methods are convenient and flexible, and the resulting designs are good choices for computer experiments.
