Dear Michiel,

Thank you very much for your guidance! I’m so sorry, but I still have two follow-up questions:

1. I plan to use the estimated parameters from the pilot study as the starting values for model estimation in the main study. Is this approach correct?

2. In a labelled experiment, I set ...

Dear Michiel,

Many thanks for your thorough and insightful response. It has been very helpful. I’m sorry to bother you again, but I still have two follow-up questions:

1. For a Ngene joint model with forced and unforced choices, is the total number of Bayesian priors equal to the sum of the priors ...

Dear Michiel,

Here is my labelled experiment: three labelled alternatives and an opt-out option. The three alternatives, optA, optB, and optC, represent different new methods. A forced choice question will be displayed if respondents select the opt-out option. I dummy coded all attributes and set ...

Dear Michiel,

Thank you very much for your valuable insights.

Dear Michiel,

Thanks for your detailed explanations! I’m sorry, but I still have a few follow-up questions:

1.1 In the Ngene pilot study syntax above, I set the constant for the opt-out alternative to zero and omitted its utility function. In this case, can I still estimate a joint model, since a ...

Dear Michiel,

Thank you again for your earlier replies. I still have a few questions below:

1. I included an opt-out alternative in this labelled experiment. If respondents select “None,” they are presented with a follow-up forced choice among “optA,” “optB,” and “optC.” For model estimation ...

Dear Michiel,

Thank you very much for your prompt and valuable feedback.

Dear Michiel,

Thank you for your detailed and helpful explanations! I’m sorry to bother you again, but I still have a few follow-up questions:

1. In the pilot study, all attributes were dummy coded. After obtaining the actual prior values from this pilot study, do I still need to use dummy coding ...

Dear Ngene team,

I am new to DCE and plan to conduct a pilot study using a D-efficient design. Specifically, it will be a labelled experiment with three labelled alternatives and an opt-out option. The three alternatives, optA, optB, and optC, represent different new methods. I read manual and ...
