Interaction terms are just variables, we (humans) think they are special because we know they mean something different, but Stata just treats them as variables and that is fine: Computers do computing, humans do interpreting, and for computing you don't need to make a distinction between interaction terms and other types of variables. The ATS website has resources on how to interpret results with interaction terms, see for instance: http://www.ats.ucla.edu/stat/stata/webbooks/reg/ http://www.ats.ucla.edu/STAT/stata/code/graph_concon_int.htm Hope this helps, Maarten ----------------------------------------- Maarten L.
