Hi Michiel

Thank you for your reply. I have a question about utility functions in relation to design and estimation.
When designing a utility function with specific attributes, should the utility function used for model estimation also include these specific attributes?
Alternatively, is it ...

Hi Community,

I have a question about choice experimental design and choice estimation.

Can we exclude or remove some attributes from the experimental design of a choice model to improve the estimation results? This would mean that the attributes included in the experimental design differ from ...

Hi Michiel,

Thank you so much. It’s quite clear for me.
Another question about S-estimation in Ngene.
I’m wondering about fixed- and mean- value for a sample size. What is the difference?
What number should I need to use for a minimum sample size for the main study?

Dear experts,

I'm in the process of planning an experimental design in Ngene, and I have a couple of questions related to creating an efficient design. I'd appreciate your insights on the following:

(1) Can I modify the type of variable in the utility function from the pilot study design to the ...
