Sample size test

Hello,

I ask myself how to conduct sample size tests for discrete choice experiments. I found a paper with a code for R, but is doesn`t work. Is there any posibility to do it in nlogit or with stata?

Best regards
Michael

Re: Collinearity in Labeled Choice Experiment

Thank you very much.

So after collecting data, how can I estimate the coefficient for travelling distance digital when it is not allowed to use dummy or effects coding?

Re: Collinearity in Labeled Choice Experiment

Thank you Michiel,

can you justify this with statistical arguments? I have to answer a reviewer who says that this is not possible without causing collinarity.

Best regards,
Michael

Collinearity in Labeled Choice Experiment

Dear all,

please imagine the following labeled choice design for credits in developing countries:
- alternatives credit house bank, credit online bank
- attribute travelling distance:
--> for house bank the levels are: 5,10,15 kilometers
--> for online bank the levels are: 0.5 and 1 kilometer ...
