nolhDesign {DiceDesign}

Cioppa's Nearly Orthogonal Latin Hypercube Designs

Description

This function generates a NOLH design of dimension 2 to 29 and normalizes it to the selected range. The design is extracted from Cioppa's NOLHdesigns list.

Usage

nolhDesign(dimension, range = c(0, 1))

Arguments

dimension

number of input variables

range

the scale (min and max) of the inputs. Range (0, 0) and (1, 1) are special cases and call integer ranges (-m, m) and (0, 2m). See the examples

Value

A list with components:

n

the number of lines/experiments

dimension

the number of columns/input variables

design

the design of experiments

Author(s)

T.M. Cioppa for the designs. P. Kiener for the R code.

Examples

## Classical normalizations
nolhDesign(8, range = c(1, 1))
nolhDesign(8, range = c(0, 0))
nolhDesign(8, range = c(0, 1))
nolhDesign(8, range = c(-1, 1))

## Change the dimnames, adjust to range (-10, 10) and round to 2 digits
xDRDN(nolhDesign(8), letter = "T", dgts = 2, range = c(-10, 10))
