NOLHdesigns {DiceDesign}R Documentation

List of Cioppa's Nearly Orthogonal Latin Hypercubes designs

Description

A list of the NOLH designs for 2 to 29 input variables proposed by Cioppa in 2007. These designs combine a latin structure, orthogonality between the main terms and the interactions (+ squares) and reduced correlations between the interactions (+ squares).

This list combines the Excel spreadsheets published by Sanchez (see Source). It is used internally by the function nolhDesign which provides various normalizations.

Usage

NOLHdesigns

Format

A list of 5 matrices representing designs of experiments for 8 to 29 input variables:

nolh2_7:

nolh8_11:

8 to 11 input variables, 33 experiments.

nolh12_16:

12 to 16 input variables, 65 experiments.

nolh17_22:

17 to 22 input variables, 129 experiments.

nolh23_29:

23 to 29 input variables, 257 experiments.
