Hi Michiel,

Many thanks for your swift reply.

The code you wrote for the candidate set run perfectly fine on my machine. However, I forgot I changed the name for dummy_coded variables in the script that I provided you, namely, in the condition below, time for type3 should be the highest.

so I ...

Hi Michiel,

As discussed previously, I have two designs (two contexts), each with three scenarios A, B, and C. So I generated 6 Bayesian efficient designs, but I spotted something very suspicious, in each design, there are many cases (e.g.,10 out of 36 choice tasks) where one of the alternatives ...

Hi Michiel,

I really appreciate your swift reply.

Just to confirm with you:

1. I will use separate priors for the design of two contexts. But given I've only got the sample size of 48 for Context 1, the estimates and standard errors for dummy coded variable 'type' are very large compared to the ...

Dear Michiel,

I have used the design discussed above and did a pilot study with 150 participants in order to get priors for Bayesian efficient design.
In the survey, I have two contexts of choice experiments, say context 1 and context 2, the two contexts both used the status quo design discussed ...

Dear Michiel,

Thank you for your prompt response and help, I appreciate it!

Dear Prof.Bliemer,

Many thanks for your reply.

Another question on Bayesian efficient design.

I did a pilot study on this topic using a labelled design where the attribute "type" was designed as alternatives. "Time" was not included in the attribute. Levels for "cost" and "emissions" were ...

Dear all,

I am working on a choice experiment design including a status quo option and many constraints for realistic purposes.
The design has three scenarios A, B, and C; attributes are identical in the three scenarios, and only levels change slightly.

Scenario A:
•Attribute1 Type ...
