Hi Peer, Some responses below: > I would like to specify the values at which the marginal effects are calculated. > However when I use the at () option I specify the same life_earnings for all educational groups, > is it possible to specify different levels for each group? I don't think so but I could be wrong. You'll probably have to calculate the marginal effects manually if this is what you want, Greene has the relevant formula for alternative-specific variables. > In addition, I was hoping to be able to produce a figure for each educational level depicting prob(edu=1) on the y-axis > and income on the x-axis. That is, similar to Greene fig. 19.2 (Econometric Analysis, Fourth Edition). > Do you know of any useful commands in that regard? I don't have my copy of Greene at hand but are you thinking about something like: webuse choice asclogit choice dealer, casevars(sex income) case(id) alternatives(car) predict p if e(sample) scatter p income if car == 1 Arne * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
