Discrete Choice Experiment help

suryavelan — Sun, 12 Aug 2018 10:08:37 GMT

I am doing a discrete choice experiment (DCE) on JMP. I am investigating if an individuals favourite colour plays an role when grocery shopping.

I have made the DCE and I have got the responses. See the attached picture.

In the questionnaire, before the DCE, the respondents are asked about their favourite color.

However I dont know how to include the responses on the "favourite colour" into the analysis of the DCE.

All help is appreciated. Thanks.

This example on chocolate choice should be relevant. Here "chocolate preference" is added as a subject model effect.

I think you would want to add "favourite color" as a subject effect.

The pizza example in the help documentation and sample data should also help.

From your .png it looks like you are missing a subject ID column - I thought it was "respondent" but respondent #1 has 36 rows and lots of different favourite colours so that doesn't make sense.
