"If however you are set on a choice design or conjoint analysis then check out Help>Books>JMP DOE Guide>Discrete Choice Designs. Chapter 8 discusses specifying prior means and prior variance.
I hope this helps."
Unfortunately the information about the specification of the prio means and prio variance are quite poor. After reading all the information provided by JMP I actually still don't know how to use them. Is there any good example available? (Optimal Design of the Choice Experiment - JMP Blog is not really helpful as the author does not tell why he uses the values for the prio mean and prior variance.)
To impose a prohibition (aka: constraint, disallowed combination, etc.), for instance disallowing level 1 across attributes X1 and X2, in the in the Disallowed Combinations dialogue, use the following: X1 == 1 & X2 == 1 .
This same format can handle other (non-equal) prohibitions, as well as multiple attributes (for instance across three attributes as X1 == 1 & X2 == 1 & X3 == 1).
Separate prohibitions using a semi-colon.
