Dear all, I am trying to understand how to estimate an efficient design for a mixed logit model.

I reviewed NGENE appendix section and the paper Bliemer, M. C., & Rose, J. M. (2010). Construction of experimental designs for mixed logit models allowing for correlation across choice observations ...

Thank you so much John for the clear explanation.

This forum is fantastic!

One last comment. When I runed this syntax I got a high correlation (0.9) for attribute A in the first alternative vs the same attribute in the second alternative.

Can this be expected?

Thank you so much to both for your response!

:)

This is very helpful. This was my first design attempt in NGENE and I guess I did a poor job.

I have a couple of follow up question, though. I don't understand why scaling down the priors (or the levels) should improve estimation. Both utility ...

Dear all,

I am building a binary choice experiment with utilities for each alternative in expected utility form.

My model assumes that I should not have main effects with one three way interaction and one two way interaction

I have two questions:

1. When I include only the interactions NGENE ...

Thanks John, I will try that.

Thanks John for your answer. I finally managed to post my reply.

I could not follow what Pr1TT1[] stands for in your formulation.

I can see that you have three different intervals for CTT with 3 levels
each in each CTT i [,,]. Why did you set the design for those intervals?
Are you restricting the ...

Hi all,

I am building a conjoint experiment asking respondent to trade off between two risky options. I am aiming to model some of the proposed models in prospect theory for binary choice that are nonlinear in parameters? Is it possible to do this in NGENE?

In the manual it's shown how to specify ...
