Feature Level Resolution
How would you like to treat the case where the respondent narrows the
acceptable levels of a feature to only one (all other feature levels are
totally unacceptable)? Your choice may influence the respondent's relative
importance score of each feature. Relative feature importance is measured
as the value gained by moving from the least preferred level to the most
preferred level for that feature...
Combine the most preferred feature level with the next lowest level.
If there is no lower level, then the next highest level will be selected.
(Use when there is a linear or curvilinear order effect in the feature
levels i.e., more or less is worse)
Combine the most preferred feature level with a random feature level.
(Use when there is no order among the feature levels)
3. Present / Absent
Combine the most preferred feature level with a "No $InsertFeatureLevelName".
(Use when this is an all or none feature)
