createBoseBush: Create an orthogonal array using the Bose-Bush algorithm.

In lhs: Latin Hypercube Samples

Create an orthogonal array using the Bose-Bush algorithm.

Description

The bosebush program produces OA( 2q^2, k, q, 2 ), k <= 2q+1, for powers of 2, q=2^r.

Usage

createBoseBush(q, ncol, bRandom = TRUE)

Arguments

q	the number of symbols in the array
ncol	number of parameters or columns
bRandom	should the array be randomized

Details

From Owen: An orthogonal array A is a matrix of n rows, k columns with every element being one of q symbols 0,...,q-1. The array has strength t if, in every n by t submatrix, the q^t possible distinct rows, all appear the same number of times. This number is the index of the array, commonly denoted lambda. Clearly, lambda*q^t=n. The notation for such an array is OA( n, k, q, t ).

Value

an orthogonal array
