Hi & Sorry for bothering you again.
Somehow I can't find a way to create a full-factorial design for a variable number of factors (k). Same for fractional factorial design. I know how to do it if I know the number of factors, as I can use
full_factorial_design = DOE(Screening Design);
full_factorial_design << add factor;
full_factorial_design << add factor;
full_factorial_design << add factor;
full_factorial_design << add factor;
full_factorial_design << Make Design(4);
But this works only if i want to select the 4th design in the design list. This would not be the full-factorial design if I had 6 factors.
Is there any documentation about the scripting functions for the DOE-platforms in JMP? I could not find anything in the Scripting Guide or the DOE-pdf. Sadly the Scripting-Index isn't very helpful either.
Thanks for all hints!

If you want a full factorial design, you can use the Full Factorial designer:
DOE(
Full Factorial Design,
{Add Response( Maximize, "Y", ., ., . ),
Add Factor( Continuous, {-1, 1}, "X1", 0 ),
Add Factor( Continuous, {-1, 1}, "X2", 0 ),
Add Factor( Continuous, {-1, 1}, "X3", 0 ),
Add Factor( Continuous, {-1, 1}, "X4", 0 ),
Add Factor( Continuous, {-1, 1}, "X5", 0 ),
Make Design}
);
I don't see an obvious way to get the contents of the design choices from the Screening designer, so that you can see what each number design is.

Continuing the way that you started, you could iterate for the necessary number of factors.
n = 4;
full_factorial_design = DOE(Screening Design);
For( f = 1, f <=n, f++, full_factorial_design << add factor);
full_factorial_design << Make Design(n);
Hi Mark,
thanks for the reply. Sadly this does not solve my problem as Make Design(4) will be a full-factorial design for 4 factors (as it is the 4th design in the design list) but Make Design(5) is not the full-factorial design for 5 factors.
If you want a full factorial design, you can use the Full Factorial designer:
DOE(
Full Factorial Design,
{Add Response( Maximize, "Y", ., ., . ),
Add Factor( Continuous, {-1, 1}, "X1", 0 ),
Add Factor( Continuous, {-1, 1}, "X2", 0 ),
Add Factor( Continuous, {-1, 1}, "X3", 0 ),
Add Factor( Continuous, {-1, 1}, "X4", 0 ),
Add Factor( Continuous, {-1, 1}, "X5", 0 ),
Make Design}
);

Thanks a lot! That does the trick for the full factorials.
Is there any documentation on the different designs? How would I do the same thing for fractional factorials, etc? How do I select a fractional design of a specific resolution? Usually I'm good at figuring this kind of stuff out on my own, but I couldn't find any documentation on that.
Kind regards,
Sebastian
