|Details of the FACTEX Procedure
- EXAMINE <options> ;
You use the EXAMINE statement to specify the characteristics of
the design that are to be listed in the output.
The options are remembered by the
procedure; once specified, they remain in effect until
you submit a new EXAMINE statement with different options or
until you turn off all EXAMINE options by submitting just
The following options are available.
lists the alias structure of the design,
effects that are confounded with one another and are thus
You can specify (d) immediately
after the ALIASING option for a listing of the alias structure
with effects up to and including order d.
For example, the following statement requests aliases for
up to fourth-order effects (for example, A*B*C*D):
Each line of the alias structure is listed
in the form
effect=effect= ... =effect
for as many effects as are aliased with one another.
The default value for
d is determined
automatically from the model as follows:
where main effects have order 1, two-factor interactions have order 2, and so on.
For details on aliasing, see "Alias Structure"
- If you specify the model with a resolution number r in the
then d is the integer part of

then d is the larger of

- the largest order of an effect considered
to be nonnegligible
