Re: Best-Worst (Case 1) dataset development

John and Michiel,
Thank you both for your responses.

John, I made the suggested changes but am running into collinearity issues. When I try to run a conditional logit model it will omit the final variable (e.g., "E") because of collinearity. I am using STATA/IC (version 15) to conduct my analysis ...

Prior - Only know the sign (DCE newbie)

Hello all,

My question is in regards to prior values. I have read previous posts and literature on this topic but still have a couple of questions. In my study, I only know the direction (sign) of my priors. Thus, I know I want to input the sign in to get a more efficient design but am unsure of ...
