Orthogonal Array Table. The orthogonal arrays constructed with a fraction of a full factorial array but the orthogonality in dependency between the factors is kept. Orthogonal arrays with r.
Taguchi orthogonal arrays are balanced to ensure that all levels of all factors are considered equally. Eleven two level factors l16. L4 2 3 l8 2 7 l12 2 11 l16 2 15 three level designs.
In mathematics an orthogonal array is a table array whose entries come from a fixed finite set of symbols typically 1 2 n arranged in such a way that there is an integer t so that for every selection of t columns of the table all ordered t tuples of the symbols formed by taking the entries in each row restricted to these columns appear the same number of times.
L9 3 4 l27 3 13 mixed level designs. Five four level factors l18. Orthogonal arrays with r. It is a highly fractional orthogonal design that is based on a design matrix proposed by dr.
