DPMPDR Documentation

Densest packing-based maximum projection designs

Description

Generates a densest packing-based maximum projection design.

Usage

DPMPD(p,n,rotation="magic",w=100)

Arguments

p

Number of dimensions, must be an integer greater than one and no higher than eight.

n

Number of points, must be an integer greater than one.

rotation

Optional, whether to use magic rotation matrices (for p=2,3,4,6,8, recommended) or random rotation matrices.

w

Number of rotation matrices to try.

Details

This function generates a densest packing-based maximum projection design in two to eight dimensions. For p=2,4,8 with rotation="magic", the designs are generated following the Biometrika paper "Lattice-based designs possessing quasi-optimal separation distance on all projections". For p=3,6 with rotation="magic", the designs are generated following the arXiv paper "Lattice-based designs with quasi-uniform projections". For other p or rotation!="magic", the designs are generated from random rotations.

Value

The value returned from the function is a list containing the following components:

Design

The generated design.

ProjectiveSeparationDistance

The projective separation distance of the generated design, from one-dimensional projections to the unprojected design.
