Designing Fractional Factorial Design Choice ExperimentHi,
I am using JMP to create my choice profile for the discrete choice experiment. I have two attributes with 3 levels and four attributes with 4 levels. This makes the full factorial design to have 144 possible combinations. However, this one cannot include all options in the survey as it can get tedious for the respondents to answer. For this reason, I want to design my experiment using the fractional factorial method where JMP will choose a subset from the overall combination. I wanted to ask how do we create a choice design based on fractional factorial design? Are there any important things to keep in mind while JMP chooses the susbet? How do we know JMP makes the best choice of subset?
