Re: ;Reject: and ;Require: in heterogeneous design

Hi

Another follow up question.

I use the code suggested (attached below), and got a design with a situation with one alternative has the same attribute levels (other than cost) with those in the status quo. In that situation that alternative is then clearly dominated by the status quo (since cost ...

Re: ;Reject: and ;Require: in heterogeneous design

Thanks again, Michiel. I read your reply to my question on stated choice design forum and thought NGENE was able to do heterogeneous design with constraints. Obviously I was wrong.

I ran the code your provided and indeed found that the cost attribute is pretty unbalance. Any suggestions on how to ...

Hi

This is actually a follow up question from a post on Stated Experiment Design Forum. I would like to design an experiment with 2 alternatives and 1 SQ, where the attribute levels of SQ will be determined by respondents choices. For example, I have the following syntax for 3 status quo. I ...

Determine an efficient design on the fly

Hi

I would like to design a experiment with 2 unlabeled alternatives + status quo, where the attribute levels in SQ will be determined by respondents choices. First, I am thinking about what is the correct way to generate such a design. I don't think the pivot design discussed in section 8.3.2 in ...
