Subject:      Fractional factorial design
Content-Type: text/plain; charset="us-ascii"


I am dealing with a full factorial model of dimension 2 x 3^2 x 4^4 x 5 = 23.040 profiles I need to simplify to run a main-effect-only conjoint analysis. Can any of you advice on how I can get the simplified fractional factorial design by using SPSS? Or is there another software (possibly free- or share-ware) that can be used for such a purpose? I have just downloaded Fractional Design Expert and discovered it can handle up to a design of maximum of 3^7 complexity....
