addelman_const
implements the Addelman and Kempthorne construction of orthogonal arrays of strength two.
addelman_const(dimension, levels, choice="U")
dimension |
The number of columns of the orthogonal array. |
levels |
The number of levels of the orthogonal array. Either a prime number or a prime power number. |
choice |
A character from the list ("U","V","W","X") specifying which orthogonal array to construct (see "Details"). |
The method of Addelman and Kempthorne allows to construct up to four orthogonal arrays. choice
specify which orthogonal array is to be constructed. Note that the four orthognal arrays depends on each others through linear equations.
A matrix corresponding to the orthogonal array constructed.
