Software for calculating general fractional factorial design?
I'm wondering if any of you know a computer software that can perform general (multi-level) fractional factorial design (http://en.wikipedia.org/wiki/Fractional_factorial_design)?
I've looked at Axiom · Eigenmath · Mathomatic · Maxima · PARI/GP · Reduce · Sage · Yacas, Macsyma · Maple · Mathcad ·Mathematica, none of them seem to to do it. MatLab only does
So, is there any software that can do a genearl FFD?
Thanks a lot.
