[R] Conjoint in R

[Jonathan Baron]

Another approach, not mentioned yet, is to use ace, in the
acepack package.  I have used this in an article (with Andy
Gurmankin) coming out soon in Memory and Cognition, which I could
send by email.  It isn't obvious to me that this will (or that it
won't) work with a fractional factorial design; my hunch is that
it will work.

 I am trying to apply a conjoint analysis in order to determine the best
 profile that captures the most preferred combination of levels of given
 categorical factors.
 
 For this a set of factors is given and initially a fractional factorial
 design has to be produced as a subset of all possible factor levels
 combinations, sufficient to estimate the main effects utilities.
 
 Then the preference for each chosen combination is assessed via surveys on
 subjects (clients). Preferences are given by ranking profiles ordinally.
 
 Conjoint analysis then is applied on the preference data to estimate the
 utility values - or the "part worth" for each factor level.
