Hi,
I have checked many of your documentation, papers and forum answers, however I somehow can't figure it out whether my CBC design, that was generated using Sawtooth, is a full or fractional factorial design.
I have defined 5 attributes each taking 4 levels. I have 8 choice tasks with three concepts per choice task. In the CBC design report, I can see that 300 versions were generated, 2400 choice tasks in total (8 per version). However, I can't see how many concepts were created in total.
Using full factorial design, 1024 concepts should have been created, if I'm not wrong (4^5). But I am not sure whether 1024 concepts were created or how many. (Now, I am not even sure I understand the difference btw. full and fractional designs)
I would appreciate if someone could help me where to find out that information.
Thank you.
