## What is this?

An R package for estimating Structural Equation Model (SEM) Trees and Forests. They are a fusion of SEM and decision trees, or SEM and random forests respectively. While SEM is a confirmatory modeling technique, SEM trees and forests allow to explore whether there are predictors that provide further information about an initial, theory-based model. Potential use cases are the search for potential predictors that explain individual differences, finding omitted variables in a model, or exploring measurement invariance over a large set of predictors. A recent overview is in our latest book chapter in the SEM handbook (Brandmaier & Jacobucci, 2023). 

## Install

Install the latest stable version from CRAN:
```{r eval=FALSE}
install.packages("semtree")
```

To install the latest semtree package directly from GitHub, copy the following line into R:
```{r, eval=FALSE}
library(devtools)
devtools::install_github("brandmaier/semtree")

# even better: install with package vignette (extra documentation)
devtools::install_github("brandmaier/semtree",force=TRUE, build_opts = c())
```

## Usage

Package documentation and use-cases with runnable R code can be found on our github pages: [https://brandmaier.github.io/semtree/](https://brandmaier.github.io/semtree/).

Package vignettes (shipped with the package) contain documentation on how to use the package. Simply type this in R once you have loaded the package:

```{r eval=FALSE}
browseVignettes("semtree")
```
