These strategies might be: to expand on or add a new array of strengths, to explore unique territories, to strengthen competitive advantages or to explore untapped potential, to name a few.
Designs D2 and D3 are orthogonal arrays of strength 2, D1 and D4 are balanced arrays of full strength, D5 is a balanced array of strength 2, and D6 is obtained from D3 by deleting the duplicate run.
The method starts with an orthogonal array of strength 2, possibly tight, that contains mostly 2-level factors.
It is well known that a two-level orthogonal array of strength 2 is universally optimum for the estimation of main effects for uncorrelated errors.
In the interim, mobilize a stunning array of strength, close streets, empty parks, slow traffic, watch the bridges and inconvenience the populace in the process -- men and women who learned long ago that in New York one has to take it as it comes.
A covering array of strength t and order v is an N×k array over Zv with the property that every N×t subarray covers all members of Ztv at least once.
In particular, for every prime power q and every m⩾2 there exists a unique (up to equivalence) complete linear orthogonal array of strength two associated with the classical design of points and hyperplanes in AG(m,q).
For two-level factorials, we consider designs in N=2 (mod 4) runs as obtained by adding two runs, with a certain coincidence pattern, to an orthogonal array of strength two.
A k × N matrix A with entries from a set X of s ≥ 2 symbols is called an orthogonal array of strength t, size N, k constraints, and s levels if each t × N submatrix of A contains all possible t × 1 column vectors with the same frequency λ.
