Hello,

I am doing for the first time a labeled choice design where I have 3 products (cow, plant, precision) varying for price (4 levels) only. I plan to use a simultaneous orthogonal design for the pilot study, see code:
Design
;alts = cow, plant, precision, nobuy
;rows = 16
;block = 2

Hello,

I am reviewing a paper where authors have used a choice design with food products (unlabeled choice experiments) which have created 15 choice sets which they divided into 2 blocks of 8 and 7 choice sets. Thus, one a group of consumers get 1 block of 8 choice sets while the other group get a ...

Dear Michiel,

Thanks a lot for this reply. It was very useful.

Now in another experiment I use the Best Worst design (using incomplete block design), and I need to compare different treatments groups. How I can run power analysis to calculate the minimum sample sizes of the treatments?

Thanks ...

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 ...
