modelling minimal design DCEs

My colleagues and I conducted a DCE with a minimal D-efficient design. In other words we used as less choice sets as possible, because our topic was very complicated and we thought that answering our choice sets was highly cognitively demanding.

Currently we are modelling our data and I have a few ...

Re: Efficient design and ASC

Hi John,

Thanks for your reply, this helps indeed!

What I meant with respect to the generic constant is that I would like to include a constant for option A and B together as opposed to the opt-out. Since all my attributes are effects coded, this constant will then tell me the preference of the ...

Efficient design and ASC

Hi,

Currently I’m working on a DCE project were we have used a D-efficient (D-optimal) design to develop our choice sets. I got (part) of the data now and although we had an unlabeled design, I do find a significant difference between the alternative specific constants. This is weird because ...
