does this solution work only with the functions c. ## ??can I calculate the interactions as products of variables(standardized variables) and the apply this method?

Maarten already posted a concreteexample athttp://www.stata.com/statalist/archive/2011-02/msg01240.htmlThat is, get a series of predictions for different values of themoderator and plot them as a series of lines in the (X, Y) space.So, the same question gets the same answer.Otherwise we need to see something new from you, e.g. specificdetail on how you wrote code that doesn't work, etc.Nick n.j.cox@durham.ac.uk
