Power analysis

[d.asioli]

Hello,

I need to do sample size calculations and power analysis for a choice experiment (compare different treatments groups) and I have never done it. I will be analyzing data by using Mixed Logit Model after I complete the experiment. Is anyone can help where and how to start?

Thanks a lot,

Daniele

These publications describe sample size calculations for choice experiments, and the first discusses specifically for mixed logit.

Ngene can do sample size calculations for mixed logit if you specify the model with random coefficients and appropriate parameter priors (preferably from a pilot study).
