Thank you so much for the prompt responses, valuable insights and suggestions. I have used a generic coefficient for the cost and have created the choice sets ready for survey distribution.

Thanks again.

Hello Michiel,

Thank you once again for your patience and for providing clarification.

Apologies in advance, but I have a couple of final questions:

4. Fuel costs for car are positive, not significant and have a very small contribution to utility (estimate = 0.03, se=0.134 and t-ratio=0.228). Is ...

1. I greatly appreciate your clarification, it now makes much more sense. I have selected the parameters with the smallest contribution to overall utility to be fixed (b2, b3, b4, b6, b7, b12).

2. Thanks for this. I will set them the same as in-vehicle time

3. You have mentioned that if using an ...

Hello Michiel and the Choice Metrics team,

I have a couple of questions about an unlabeled discrete choice experiment with four different transport alternatives and seven attributes. The pilot survey had an orthogonal design and a sample size of 1,600.

Question 1 I am aware that the recommended ...

Thank-you so much for your help with estimating the priors. Your explanations have been really clear and helped me understand it better.
My modified syntax for Ngene is now as follows, so will use this for the survey distribution. Sample size is 242.
Thanks again.

Thank-you so much for your continued patience Michiel. It's all quite a steep learning curve!
Just to clarify:
1. If every survey participant answered one choice task question, I would need a sample size of 3 *113 and 452 participants. If I added 6 blocks, I would need a sample size of 452 * 6 ...

Thank you so much for your help. I will use ;eff = (mnl,d,median) and will see if I can purchase Ngene through the University.
I have three more questions:
1. It seems that the minimum sample size estimate from Survey Engine are calculated as = rows x 20/scenarios. Would I be better using the S ...

Thanks again for your help and quick feedback. I have added the prior from the travel time coefficient to the wait time. I also have a few more questions:
1. The mode constant is not significant and has a large standard error. Would you recommend changing it or leaving it as asc1[(n,-0.3,0.82)]?
2 ...

Thank you very much for your quick feedback and your suggestion to increase sobol draws. It is very reassuring to know that it looks fine. I have a couple more questions.

Question 1 Wait time
From the pilot MNL, bus wait time appears positive (n, 0.01, 0.02) which can’t be correct (though it is ...

Hello Choice Metrics team,
I am new to choice modelling and I am attempting to do a labelled experiment with 2 transport alternatives with 7 attributes.
I have just collected a pilot sample consisting of 200 respondents. Each participant was presented with 5 choice questions from an orthogonal ...
