Hi everyone
I have a question about a model with constraints we are trying to run in Ngene but results in undefined D-error. We have proceeded with a few approaches to resolve the issue but have not managed to find a solution. We would really appreciate your input on this.
The main code used for ...

Dear all,
We are working on a DCE to elicit preferences for a patient reported outcome measure. Although we have reduced as much as possible the profile measure, we still end up with 13 attributes with 4 levels each. To simplify choice task complexity we plan to use an overlapping design with 6 ...
