NESTED SPACE-FILLING DESIGNS FOR COMPUTER EXPERIMENTS WITH TWO LEVELS OF ACCURACY

Abstract

Computer experiments with different levels of accuracy have become prevalent in many engineering and scientific applications. Design construction for such computer experiments is a new issue because the existing methods deal almost exclusively with computer experiments with one level of accuracy. In this paper, we construct some nested space-filling designs for computer experiments with two levels of accuracy. Our construction makes use of Galois fields and orthogonal arrays.
