Abstract: Math, when written carefully, can represent a model perfectly. Stata syntax, when written correctly, can represent a model perfectly. Everyone is supposed to understand math, but I have encountered those who do not. I personally think everyone should understand Stata syntax, but again, I have found a few who do not. Path diagrams provide an alternative formalism that is easily accessible to a wide audience. With a few conventions, we can use path diagrams to represent a variety of models and perhaps help explain those models. These diagrams are easy enough to create in Stata, so we will look at some models—both simple and difficult—to see what we think of this emerging formalism.
