I see. Thanks!

Hi Michiel,

Thank you for your detailed reply. I have one more question related to the least important attributes. The attributes I used in the utility functions are all linearly additive. For example,
V(car)=b_tt_car*ttime_car+b_parking*parking_car
V(bus)=asc_bus+b_freq ...

Dear Prof Bliemer,
I have several questions related to Bayesian efficient designs.

First, I have 16 parameters estimated in the pilot survey. However, only 7 of them are statistically significant, which can be used as Bayesian priors. I was wondering whether I can select another 3 estimations that ...

Hi

I am doing a Bayesian efficient design based on a pilot survey. I am wondering whether I should increase rows for the Bayesian efficient design. I understand that increasing rows will significantly decrease D error and S estimate. However, increasing rows also means I have to add choice tasks in ...

Hi Michiel,
Many thanks for your detailed reply. Now, I understand that if assuming uncertain priors follow normal distributions, I should use estimated betas in my pilot survey as means and standard errors as standard deviations. I still have two questions regarding to ...

Hi

I am doing a bayesian efficient design now. However, I don't know how to determine distributions for uncertain priors in my design. For example, for what type of priors I can assign a normal distribution or uniform distribution? In addition, if I assume one prior follows a normal distribution ...

Hi Michiel,

Many thanks for your reply. Could I ask another simple question? One of my attributes is frequency of service, whose levles were assigned as every 5, 7.5, or 10 min. My question is that whether this type of attributes is continous variable. I am confused with ...

Hi Michael,

Many thanks for your detailed reply. The travel time of bus and metro in my survey design are not fixed either. Their attribute levels are pivoted based on each respondent's reported travel time in bus and metro, respectively. However, I didn't know how to ...

Hi,

I am doing a stated preference experiment designs in Ngene. In my choice experiments, there is a status quo alternative (altcar) out of three alternatives, whose attribute values are determined by answers extracted from previous questions. I use an alternative specific constant in utility ...
