Dear colleagues

I have run an unlabelled choice experiment with 2 alternatives + SQ option, 2 attributes A and B + 1 monetary attribute C.
Attribute A has 3 levels, dummy-coded 0, 1, 2
Attribute B has 2 levels:, dummy-coded 0, 1
Attribute C has 5 levels
I asked respondents what are their current ...

Please let me being more precise on the second question

This code, with less information on priors, is running.

Design
;alts=GA*, GB*, SQ
?place an asterisk next to the names to prevent from having i) within choice task alternative repetition, ii) strict attribute level dominance and iii) choice ...

Dear Ngene community,

I have collected priors from a subsample of n=25. However, I am pretty sure this subsample is biased and may be less reluctant towards one of the level (attribute B=1) than the targetted population. What is the best way to deal with that ?

Here is the design I have in mind ...

Dear Michiel
Thanks a lot for your answer. I now understood that bayesian efficient design can be generated based on pilot estimates from MNL.
I have another question
In the bayesian efficient design based on MNL model I have now generated, many of the price (D attribute) and indemnity (C attribute ...

Dear all,
I have read with interest the posts concerning bayesian efficient design and modified federov to add constraints, but I could not find any answer to the following question:
Why can Ngene not find a bayesian efficient design with the following structure ?
Priors are based on RPL estimation ...

Dear colleagues

Do you have any advice on what is the more important to randomize across respondent s in DCE ?
- attribute ordering (but each respondant see the same order in every choice task to reduce cognitive burden)
- order of appearance of choice tasks
- order of appearance of alternatives (A ...

Thanks a lot Michiel.
Looking forward to the forthcoming default stopping criterion in Ngene to help us saving energy !

Dear Ngene community
I am running the efficient design below but my question is more general.
According to the manual, "Many syntax runs will execute for a long time or indefinitely. A syntax run can be stopped at any
stage by selecting the Stop menu item.". But it doesn't say when stopping is ...

Dear Julia and Michiel

I think I have a similar question but I would like to verify I correctly apply Michiel's recommandation

I have an unlabelled experiment, with 2 alternatives + opt-out option (= no insurance).
For only one of the attribute (A), the level of the status quo is also a level ...

Thank you so much for your fast, precise and reinsuring answer (5 days from launching data collection !).
I will take into account your advice when estimating WTP
Best regards,
Marianne
