Hello,

I am trying to create a design for a hard apple cider choice set. We will have two alternatives and a "neither of these products" option. We will run a random parameters logit model and calculate WTP by taking the attribute coefficient and dividing by the negative of the price coefficient ...

If I generate an S-estimate of say, 1,000, but only can afford 300 observations, does this mean I need to find a new design?

Thanks! I have reduced my design to 2 blocks and 12 choices each. I have also added the asterisks after the alternatives. How can I make the design assume each respondent only sees 12 choices (1 block)? We only want respondents to see 12 choice sets each.
By the way, I'm now working with the ...

Thanks! I decided to get rid of the Bayesian restriction and it is running much quicker now. I now have another question. I have made some adjustments to the previous code and now get a decent design with a D-error, etc. However, for D-optimality it returns 0%. Since I'm doing an efficient rppanel ...

I am trying to generate a RP-panel efficient design using priors. However, it has been running for four days and it still hasn't found a design. You responded the following to help:

"I would suggest moving incrementally to a full RP-panel design. Add one random parameter at a time, without Bayesian ...
