Subject   st: Generate Estimates for Dependent Variable using OLS Regression

I am trying to use the "pick a point method to create a visual figure
– in Excel – of the interaction between risk propensity (zriskprop)
and religious salience (zrelpriv) as they relate to my dependent
variable: problem behavior (problem).

This is my syntax for the regression equation:

svy: reg problem age2 sex black hispanic otherrace inc1 inc2 inc3
nofather droppedout depression anxiety zriskprop zservice zrelpriv
zriskprop_zservice zriskprop_zrelpriv

My dependent variable is problem behavior (problem) and the
significant interaction term is “zriskprop_zrelpriv”.  If I wanted to
graph the interaction for low, moderate, and high risk propensity as
related to religious salience, I believe I would need to generate
estimated values of my dependent variable (problem) when my IV (risk
propensity) is at values of -1SD, 0, and +1SD (or some equivalent),
right?

The problem is this: I can't figure out how to generate these
estimates of values of my DV when stipulating the my IV is at
particular values.
