Dear Michiel,

Thank you very much for your advice!

Best regards,

Dear Choicemetrics team,

Some months ago I asked you for advice regarding the design for my research. My data collection went very well and I am very thankful for having been able to count on your expertise!

Now I'm planning to do a new survey for a comparative study in another area, where the ...

Dear John,

thank you very much for your advice! Letting my colleagues complete the choice tasks is a great idea!

Again, thank you and the rest of the Choice Metrics team for this great service.

Best regards,

Dear John,

thank you very much for your reply and valuable feedback!

Since I'm trying to generate a design for a pilot study, from which I intend to obtain parameter priors, what do you suggest should I do:

i) go ahead with the pilot using the non-bayesian efficient design that I produced with ...

Dear Michiel,

thank you very much! Indeed reducing the values of the yield and costs priors fixed the problem! I modified the levels of the cost attribute and added some constraints to obtain more realistic scenarios, as follows:

Design
;alts = proj1*, proj2*, stquo
;rows = 12
;eff = (mnl,d ...

Dear Michiel,

following your advice I'm now trying to generate an efficient design. As recommended in the manual, I wrote the syntax for a simple non-Bayesian design for a MNL model (before generating a more complex Bayesian design), in which I assign small values and the corresponding signs to the ...

Dear Michiel,

thank you very much for answering all my questions in such a quick fashion and I apologize for asking so many of them, especially because most of them could have indeed been answered by consulting the extended literature on experimental design theory. I doubt though that such answers ...

Dear Choice-Metrics team,

First of all I would like to thank you for developing Ngene and for releasing such a great user manual! It not only explains the software package very well, but also provides more insights on experimental design theory for stated choice experiments than most of the ...
