Dear Bryan, Thanks again for answering my question. Its clear now.
Another part of the question which I asked before:
In Market Simulator, in the "Prohibition" section, there are two check boxes under "Prohibition Enforcement behavior". As my survey already had prohibitions before which stopped the respondents seeing specific combinations, will not checking these boxes help allow me to reconfigure different combinations in the scenario builder even if those combinations were not possible with the original survey?
Plus, the constant which is a part of the utility function is not shown in the HB estimates. Could you please advise on which variable is this captured in the individual level HB estimates?
