Can the unweighted share calculated from the utilities of a volumetric conjoint be considered equivalent to preference shares from a DCM?
I understand that we weight respondents by the max volume on any screen to get to the volumetric distribution SKUs tested, and create none based on remainder of the max volume not allocated to the SKUs.
I want to understand if the unweighted share have any kind of interpretation / meaning, and if it can be treated same as preference share.
Do volumetric models tend to have a higher none % relative to DCM? My gut feeling is they do, because on each screen unless someone is allocating their max volume every time, none always gets a piece of the share, inflating it's utility.
