Re: Pivot design - number of respondents
Regarding sample size, the only proper way to compute it is via parametrer priors and predicted standard errors. Ngene automatically computes sample size estimates based on priors provided in the syntax, I refer to Rose and Bliemer (2013). These priors typically come from a pilot study using the ...

Pivot design - number of respondents
Hi all,
I have question regarding the required number of respondents for a pivot design, and consequences for estimation. In our experiment respondents choose between purchasing an 'electric vehicle' and a 'conventional car'. So 2 alternatives in the choice set. The price attribute for the car is a ...

Re: Context - include as interaction effect?
Thanks for your comments.
1. You cannot simply set the utility of an alternative to zero, except when it represents an opt-out (no choice). In your case, the alternative represents a plane trip and therefore has attributes, namely it has a travel time and a travel cost, and perhaps you need to ...

Context - include as interaction effect?
Hi all,
I am new to choice experiments and Ngene. I am using it for my thesis at the university. I had a introductory course into choice experiments in which Ngene was used. What I want to do is estimate the willingness to use night trains for travel within Europe. I got 3 alternatives: night train ...
