use 3d surface graph to explain in*the interaction effect

[Raymond Zhang]

Dear all,@Nick Cox Can i use stata command to plot a 3d surface graph to explain in the interaction effect? For example,My model is y=b0+b1*x1+b2*x1*x2+e, can I plot a graph to explain the effect of x2 to the effect of x1 on y?Such as this picture:

I do not think you can do that directly in Stata, unless you use exploit the capabilities given by the integration of python in Stata. See this example for instance: https://blog.stata.com/2020/09/14/st...l-predictions/

There is the community-contributed surface command but you need to invest some effort yourself to set up a data set with the effects you want to plot:

ssc install surface

The graph3d command may also be helpful:

ssc install graph3d

Not a surface but possibly of use as well are twoway contour graphs that are part of official Stata.
