YATES CUBE PLOT

Name:
    YATES CUBE PLOT
Type:
    Graphics Command
Purpose:
    Generates a Yates cube plot.
Description:
    The Yates plot is used in the design of experiments for 2-level full or fractional factorial designs. It is used in the case where you have three independent factors, each with two levels. The low level is coded as "-1" and the high level is coded as "+1".

    This command draws a cube with vertices corresponding to either -1 or +1 for each of the three factors. At each vertex, the average of all the response values corresponding to that vertex is printed near that point. For example, at the vertex point (-1,1,-1), the average value for the response variable for all points where X1=-1, X2=1, and X3=-1 is printed.

Syntax:
    YATES CUBE PLOT <y> <x1> <x2> <x3> <SUBSET/EXCEPT/FOR qualification>
    where <y> is the response (= dependent) variable;
    <x1> is the first factor (= independent) variable;
    <x2> is the second factor (= independent) variable;
    <x3> is the third factor (= independent) variable;
    and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
    YATES CUBE PLOT Y X1 X2 X3
    YATES CUBE PLOT Y X1 X2 X3 SUBSET X4 = 4
Note:
    The appearance of the plot is controlled by the settings of the LINE and CHARACTER command. In addition, you can use the attribute settings for LINE and CHARACTER (e.g., color, thickness) to further control the appearance.
Note:
    The Yates cube plot can be extended to the 24 and 25 cases by using it with the CONDITION PLOT command. See the Program 2 and Program 3 examples below for details.
