I am designing a discrete choice experiment. I want to create profiles which exist of 4 attributes.
I have 7 attributes, 3 with 2 levels, 3 with 3 levels and 1 with 4 levels.
I need to take two steps:
Step 1: Determining the constant attributes in each choice set, I want 4 of the 7 attributes in each choice sets.
I created a BIBD with %mktbibd
No i am arrived at step 2, how can I determine the attribute levels of this BIBD design (balanced and orthogonal)?
Step 2: Determining the levels of the non-constant attributes.
Can someone help me with step 2?
