However, when I create "cost" as a continuous variable, the choice sets generated only included the highest and lowest levels (no in-between) for for the cost variable. The commands are as follows: matrix levmat = 3,3,3,3,3,3,4. genfact, levels (levmat) Webb2 sep. 2024 · First of all, I want to thank you for your helpful command “dcreate”. I am a PhD student and I am using a discrete choice experiment (DCE) for measuring willingness to pay. I want to ask about the dimension of matrix of estimators (bmat), since I have 4 attributes x1,x2,x3,x4 and I am assuming interaction effects between x1 and x2.
