A scrambled 3D orthogonal array of strength 2

Description

This design is obtained by adding a uniform noise to each coordinate of the orthogonal array OA131.

Usage

data(OA131_scrambled)

Format

A data frame with 49 observations on the following 3 variables.

x1

first coordinate

x2

second coordinate

x3

third coordinate
