I'm attaching the description of a proprietary version of Conjoint Analysis I developed around 2000-2010 extensively using SAS prototyping. The final version has been done on two platforms (1) by ASKIA personnel on their data collection platform for running the interviews. I just consulted for that (2) Visual Basic 6 for Design, Estimation and Simulation. This package wouldn't exist without the lengthy prototyping that allowed to discard a number of apparently promising approaches.
I decided to let people know about because this package shortens a lot the tough task of Conjoint Cards evaluation.
