Re: Endpoint Unlabeled Efficient Bayesian Design

Dear Michiel,

So in the case where priors are not accurate and one is ought to ignore the S-estimate, what constitutes the sample size for an experiment that is intended to use either Latent Class or Panel-Mixed-Logit?
I know that in the aggregate estimation using MNL model, a sample size rule of ...

Re: Endpoint Unlabeled Efficient Bayesian Design

Dear Michiel,

Thank you for your help. I have one more question that is related to experimental design.

I did add the ;alg = mfederov(candidates = 1000) and the results are great.

However, when I tried to run the design using priors from another pilot (with a smaller sample, n=30, and most ...

Re: Endpoint Unlabeled Efficient Bayesian Design

Dear Michiel,

In the calculation you mentioned, I know that all possible combinations = 2^5 * 2^2 * 2^5 = 32,768
Could you please tell me how did you get the 6,540?

Thank you

Endpoint Unlabeled Efficient Bayesian Design

Dear All,
I am constructing choice sets for an unlabeled experiment. I have 5 attributes each with two levels.
I conducted a pilot study using an optimal design. The pilot had two alternatives and a no-choice option. The total choice sets were 16 divided into 2 blocks. So, every participant ...
