In the rest of this blog entry, i will show you examples of path diagrams:ġ. Here is an example of what it could look like: Path diagrams consist of rectangles for observed variables, ellipses for latent variables, curves with arrow-heads on both sides for correlations and most important: straight lines with arrow-heads on one end as paths, that link a predicting and a predicted variable. It seems to me, that – at this point – this will generate the highest quality path diagrams.

As a third solution, you can just use usual graphics software and type parameter-estimates by hand. When it comes to the R-packages, there are significantly better attempts to generate visualisations of structural equation models. Especially if your model is a little bigger. In my experience the other SEM-tools (LISREL,MPLUS,STATA) don´t produce very appealing diagrams. Sometimes you can find these AMOS path diagrams beeing published in articles. This can make it easy, especially for beginners. AMOS is a special case, because the modeling is done via drawing path diagrams. Most of these solutions have a built-in possibility to visualize their models. LISREL, AMOS, MPLUS, STATA, SAS, EQS and the R-packages sem, OpenMX, lavaan, Onyx – just to name the most popular ones.

There are many software solutions to do structural equation modeling. In this post, i´ll show a selection of tools and their output. The automatically produced path-diagrams are often good enough as you work out your model, but they´re not polished enough for publication. As structural equation models can become complex and contain a lot of parameters to describe the relationships between observed and latent variables, it´s an important step to visualize them properly. A path diagram is kind of like a flow-chart that uses arrows to show direct and indirect causal links between your exogenous and endogenous variables, as well as your latent and your observed variables. They are an important means to give your audience an easier access to the equation system, that represents the theory you want to test. Visualisation of structural equation models is done with path diagrams.
