The design is comprised of four attributes (5*3*3*3) with the following 5 price 3 brand 3 service 3 installation I need to determine the minimum no of choice tasks which can be used to estimate main effects for each attribute and then actually generate these choice tasks to be included in the survey SPSS has orthoplan but only generates these tasks for a traditional conjoint design, not for conjoint based choice tasks A partial factorial design is what I had in mind .........................
