Hi John,

everything clear! Many thanks!

Just to be sure I understood how to handle with dominanted alternatives in efficient designs: I will soon develop a d-efficient for my final survey - the orthogonal design is just for the pilot survey to collect priors' information - and I would like to make ...

Good morning,

I am writing you concerning one problem of dominant alternatives that I encountered in the development of the orthogonal design that I will employ for the pilot study of my project. In principle, by using the command * after listing the alternatives in the Ngene instructions, the ...

Thanks a lot Michiel!

Best regards,

Thank you very much Michiel! Yes, you are right, I meant a quadratic form of the attribute.

Best wishes

Hi everybody,

we are planning to enter one of our quantitative attributes in non-linear form in the utility specification of the design's alternatives. I only found the "dummy" solution in the Ngene manual but we would be interested in employing a quadratic specification of the variable. Is there ...
