Thnks, Maarten. I have replicated the graph successfully with my data.
The tricky part is that one of the variable that I allow to change,
(holdind the rest at means), has interaction. Now the interaction is
left at means. I suppose, in this setting the graph is only telling
half the story (better than nothing). The next question is, how can I
include a command in there, to instruct stata to keep the dummy
variables at their observation value, while maintaining means for the
continous variables.
Much, thanks, James.
