[R] Design of experiments for Choice-Based Conjoint Analysis (CBC)

You might find the attached article useful.  I am facing the same 
problems that you appear to be facing, and I found this article to be a 
great help.

I've also attached a small script I wrote to replicate the analyses 
presented in the paper. I can't reproduce the second analysis though, 
and I can't figure out what's wrong with my code.



P.S.  Is anyone else lurking interested in Discrete Choice Experiments 
and/or MaxDiff (Best/Worst) scaling.  Perhaps we could form a wee SIG?



P.S.  While there is no single function to do CBC/DCE in R, it doesn't 
seem too hard.  The only step for which there is no single function is 
aggregating the design matrix and data.  I've named my script/function 
MktRoll after the SAS macro that does that same job  (among many other 
things, I'm sure).  It's just a quick hack, though!

While it seems to be relatively straightforward in R, I have yet to 
actually implement a design and gather and analyse the data though ... ;-)
