SPSS's conjoint module could tackle this. You could also try SYSTAT (30 day demo available at http://www.systat.com). If you have the SAS IML procedure you can use their DOE software. Also try Sawtooth CVA software (http://www.sawtoothsoftware.com). Mike on 9/6/05 6:12 AM, Luca Meyer at lucameyer@tiscali.it wrote:
