OLHD.L2009: Orthogonal Latin Hypercube Design

In LHD: Latin Hypercube Designs (LHDs)

Description

OLHD.L2009 returns a n^2 by 2fp orthogonal Latin hypercube design generated by the construction method of Lin et al. (2009)

Usage

OLHD.L2009(OLHD, OA)

Arguments

OLHD	An orthogonal Latin hypercube design with run size n and factor size p, and it will be coupled with the input orthogonal array.
OA	An orthogonal array, with n^2 rows, 2f columns, n symbols, strength two and index unity is available, which can be denoted as OA(n^2,2f,n,2).

Value

If all inputs are logical, e,g. a n by p orthogonal Latin hypercube design and an OA(n^2,2f,n,2) orthogonal array, then the output will be an orthogonal Latin hypercube design with the following run size: n^2 and the following factor size: 2fp.
