Constants only Labeled DCE

Hello everybody,

I have a question regarding a labled choice experiment. I know binary DCEs, where the decision is to accept the combination of attributes or not. Levels vary only between choice sets. But my setting is a bit different. I have three alternatives. The levels of all attributes are the ...
