Scidoe designs

An overview of the designs.

Purpose

The goal of this document is to present the designs which are available in this toolbox.

Central Composite

x = scidoe_ccdesign(2)
scf();
plot(x(:,1),x(:,2),"bo")
xtitle("Central Composite Design","X1","X2")

Box-Benkhen Design

// Create a Box-Benkhen Design with three
// variables one repetition of center:
H = scidoe_bbdesign(3)
// Plot the design
h = scf();
param3d(H(:,1),H(:,2),H(:,3))
h.children.children.mark_mode="on";
h.children.children.line_mode="off";
h.children.children.mark_size=1;
scidoe_plotcube(3)
xtitle("Box-Benkhen Design","X1","X2","X3")

Full Factorial Design

// Create a full factorial design with :
// 2 levels for the first factor
// 2 levels for the second factor
B=scidoe_ff2n(2)
// Scale into [-1,1]
C=2*B-1;
// Plot this design
scf();
scidoe_plotcube(2);
plot(C(:,1),C(:,2),"bo");
xtitle("Full Factorial Design","X1","X2")

// For three factors
B=scidoe_ff2n(3)
// Scale into [-1,1]
C=2*B-1;
h = scf();
param3d(C(:,1),C(:,2),C(:,3))
h.children.children.mark_mode="on";
h.children.children.line_mode="off";
h.children.children.mark_size=1;
scidoe_plotcube(3)
xtitle("Full Factorial Design","X1","X2","X3")

Fractional Factorial Design

H = scidoe_fracfact("a b ab")
h = scf();
param3d(H(:,1),H(:,2),H(:,3))
h.children.children.mark_mode="on";
h.children.children.line_mode="off";
h.children.children.mark_size=1;
scidoe_plotcube(3)
xtitle("Fractional Factorial Design","X1","X2","X3")

Latin Hypercube Sampling Design

H = scidoe_lhsdesign(2,5)
scf();
scidoe_plotlhs(H)
xtitle("LHS design","X1","X2")

Star Design

H = scidoe_star(2)
h = scf();
plot(H(:,1),H(:,2),"bo")
scidoe_plotcube(2)
xtitle("Star Design","X1","X2","X3")
