I have a question regarding the HB estimation of max-diff utilities.
In HB estimation, information is used from both the respondent itself as well as the entire population (I assume that this is the case since the respondent itself has only seen a part of all possible combinations)?
I was wondering how much the share of the population is compared to the share of the respondent itself in the calculation of the utilities for each respondent.
When comparing max diff results across several breaks, e.g. age groups, we generally notice not that much differences between the groups. I was wondering if this has to do with the fact that information of the population is used as well in the HB estimation? Are the utilities mainly driven what the respondent has answered or has the population also a quite high influence in the estimation?
