Appending kth Column

Given a (linear) ordered orthogonal array OOA(M, s, Sb, k−1, k) with k ≥ 2, a (linear) OOA(M, s, Sb, k, k) can be constructed.

Construction

The new OOA Aʹ is constructed as follows base on A: Let σ denote a permutation of {1,…, s} without fixed points. Then Aʹ is given by

Aʹ = {(xi,1,…, xi,k−1, xσ(i), 1)i=1,…, s  :  x ∈ A}.

If A is linear, a generator matrix of Aʹ can be obtained in a similar way.
