Re: Efficient design with zero priors or near zero priors

Dear Professor Bliemer,

Some months ago I asked you for advice regarding the pilot design for my research. I really appreciate your time and help. My data collection (150 respondents) went very well and all significant, I am very thankful for having been able to count on your expertise!

Now I’m ...

Re: Efficient design with zero priors or near zero priors

Dear Naji,

Thank you very much for explaining the different approaches for incorporating the influence of x6 in the model.

The reason I cannot include all six attributes is due to the strict constraint that the sum of all conditions equals 50. If we consider the coefficients of all attributes, it ...

Re: Efficient design with zero priors or near zero priors

Dear Professor Bliemer,

Thank you very much for your detailed explanation and insightful suggestions on exploring the multiple discrete-continuous choice model (MCDEV). I will take the time to learn and consider this method to see if it can be applied effectively in my current research ...

Efficient design with zero priors or near zero priors

Dear Professor,

I am currently designing a Discrete Choice Experiment (DCE) pilot study using Ngene. The design includes 18 choice tasks per respondent, with a total of 6 blocks of choice cards (24 cards in total). Each respondent will receive 3 choice cards. In this pilot study, I assume the ...

Re: Pilot study design for bayesian efficient design

Dear Michiel

Thank you very much for your suggestions and I really appreciate your very helpful reponse.

If I understand correctly, you suggest that I initially assume dummy coding for all attribute levels in a pilot study when using (near-)zero priors. I should then calculate the pilot results ...

Re: Pilot study design for bayesian efficient design

Dear Michiel

Thank you very much for your prompt and very helpful reponse last time and I got very good results for the main survey.

Currently, I am designing a new DCE pilot study.The design will include 24 choice tasks per respondent and 4 blocks of choice cards (24 cards in total). Each ...
