# DirectEffects 
[](https://github.com/mattblackwell/DirectEffects/actions)
## Overview
DirectEffects is an R package to estimate controlled direct effects (CDEs), which are the effect of a treatment fixing a set of downstream mediators to particular values. As of now, the package supports sequential g-estimation and a two-stage matching approach called telescope matching. For more information on how CDEs can be useful for applied research and a brief introduction to sequential g-estimation, see [Acharya, Blackwell, and Sen (2016)][de-paper]. For more on the telescope matching procedure, see [Blackwell and Strezhnev (2022)][tm-paper].
## Installation
You can install DirectEffects via CRAN for the current stable version or via GitHub for the development version.
```{r}
# Installing from CRAN
install.packages("DirectEffects")
# Installing development version from Github:
# install.packages("devtools")
devtools::install_github("mattblackwell/DirectEffects", build_vignettes = TRUE)
```
## Usage
The main functions for estimating CDEs in DirectEffects are:
- [`sequential_g()`](https://mattblackwell.github.io/DirectEffects/articles/DirectEffects.html): estimate controlled direct effects using two-stage linear models.
- [`telescope_match()`](https://mattblackwell.github.io/DirectEffects/articles/telescope_matching.html): estimated controlled direct effects using a two-stage matching procedure with bias correction.
DirectEffects also provides diagnostics for these two approaches, including sensitivity analyses and balance checks.
