I have 6 attributes in which there is a constraint that in one card in one option if we have given 2nd Level of the 1st attribute then few levels of another attribute can’t be there in the same card.
For example, there are 2 attributes: Colors and Offers. Say, Color has 2 levels Black and White; and offer has 4 levels 0, 10, 20, 30. So the constraint is that; Black has only 2 offers 0 or 10; and White has another 2 offers 20 and 30.
This is just an example; because the actual scenario has little more attributes and levels with constraints.
I want to know if this is a normal constraint, which happens to be there in all the conjoint studies or it’s only in my study and so I need to make some changes.
I am looking for a function within Conjoint library in R which “considers these constraints” unlike expand.grid and caFactorialDesign.
