Dear all,

I am looking for a software for the evaluation of factorial designs of
experiments.
For instance, I have 6 factors (experimental parameters) on 2 levels each
(+, -). I want to calculate the effects of each single factor, and the
2-(3,4,etc.)factor interaction effects, etc.
Of course, I could prepaire a spread sheet in Excel, but it seems to be a
lot of key typing for larger numbers of factors, and I had to do it again if
I add one factor to the experimental design, for instance, or make other
changes.
Can someone recommend a software package?

Best regards

Burkhard
