I also uploaded some model specifications and the results I want to replicate + the random dataset (long format) I'm using. The zip file is here: https://docs.google.com/leaf?id=0B09M2qtL2eXjNmE3ZGM4NGQtZjE4Ny00NmQzLWI3ZTEtZjYxZjI1NTM1ZGQw&hl=en Basically, I have 400 respondents. Each respondent faces 4 choice scenarios, and in each scenario he chooses among 3 option. Each option is characterized by 4 attributes (3 categorical [attr_1, attr_2 and attr_3], and 1 continuos [cost]) The respondent choice depends by the option characteristics (conditional to the characteristics of the other options in the same set) + the respondent socioeconomics.
