I?m very glad to see the Conjoint Package for R. The documentation for it does
not appear to specify methods for data acquisition. Are the cards to be
individually scored by each respondent (most clients would rather see a
choice-based methodology)?
SurveyGizmo, an excellent online survey host which I use, has in beta a Conjoint
question type. However, it does not appear to calculate respondent-level utility
values at this time.
SurveyGizmo supports a conjoint question design in which each respondent is
shown 3 cards at a time, and permitted to identify one of the three as Best, and
one as Worst. (SG supports additional conjoint question designs as well).
Data acquired by SurveyGizmo conjoint looks like this for each respondent:
> Set #1
> Model Attribute Model Value
> Price $300
> Size 7"
> Memory 128 gb
> Score: 50
>
> Set #2
> Model Attribute Model Value
> Price $100
> Size 4"
> Memory 16 gb
> Score: 0
>
> Set #3
> Model Attribute Model Value
> Price $200
> Size 6"
> Memory 64 gb
> Score: 100
>
> Set #4
> Model Attribute Model Value
> Price $100
> Size 5"
> Memory 32 gb
> Score: 100
>
> Set #5
> Model Attribute Model Value
> Price $200
> Size 5"
> Memory 32 gb
> Score: 0
Score 100 = Best
Score 50 = Not selected
Score 0 = Worst
Is it possible to use R-Project Conjoint Package with such a data file, to
calculate respondent-level utility values?
Thanks very much in advance to all for any info!
Best,
