Kowalick Arrays Result in Taguchi Testing Sometimes

Dr. Kowalich modified some of the Taguchi arrays in order to give more factors for testing without regard to factor interactions. To this end, he used the L₁₂(2¹¹) and L₁₈(2¹ X 3⁷) due to these arrays having the interactions distributed evenly across the array columns. Here is a list of the Kowalich arrays. Read more
