Title: Choosing a Strength Three Orthogonal Array to Estimate Interactions
Author(s): Robert W. Mee*+
Companies: The University of Tennessee
Address: , Knoxville, TN, 37996-0532,
Keywords: Design of experiments ; Foldover ; Generalized resolution
Abstract:

The most common strength three orthogonal arrays are formed by foldover of a Hadamard matrix. For example, Miller and Sitter (2001) advocated the use of the 24-run foldover design for up to 12 factors. The generalized resolution of these designs depends on the correlations among two-factor interaction columns constructed from the Hadamard matrix. This talk will summarize the best of these even, strength three orthogonal arrays, and make a comparison between their projections and the even/odd strength three orthogonal arrays proposed by Cheng, Mee, and Yee (2008).
