I am thinking about using the dual response none in my CBC experiment. Therefore, I have some open questions:
1. Is there any difference in defining and analysing holdout tasks when using dual response none in my CBC?
2. Can I get seperate estimates for responses of the first stage (forced choices) without directly being combined with their responses from second stage (yes/no choices)? The standard estimates are combined from responses from first and second stage, arent´t they? Is there any evidence that pooling this data in one data set violates the IID assumption? Is there any documentation available how exactly LHS is jointly extimating the responses from the two stages?
3. I assume that WTP can be estimated as with CBC experiments containing "normal" none option, right?
Any advice is highly appreciated!
