5The prediction equation for 2**k designs are of
6the form
7
8   Y = MU + 0.5*(imprtant factors)

10For example, for the 2**3 full factorial design,
11the recommended prediction equation is
12
13   Y = MU +
14       0.5*( B1*X1 + B2*X2 + B3*X3 +
15             B12*X1*X2 + B13*X1*X3 +
16             B23*X2*X3 +
17             B123*X1*X2*X3 )

19where all of the parameters will be replaced
20by the least squares estimate.
21In practice, we would include only those terms which
22turn out to be "large" (significantly non-zero), as
23determined by any of the subsequent menu items
24in this section.
