Aggregation Trees

CRAN status CRAN Downloads overall R-CMD-check

R package to implement aggregation trees, a nonparametric approach to discovering heterogeneous subgroups in a selection-on-observables framework.

aggTrees allows researchers to assess whether there exists relevant heterogeneity in treatment effects by generating a sequence of optimal groupings, one for each level of granularity. For each grouping, we obtain point estimation and inference about the group average treatment effects. Please reference the use as Di Francesco (2022).

To get started, please check the online short tutorial.

Installation

The package can be downloaded from CRAN:

install.packages("aggTrees")

Alternatively, the current development version of the package can be installed using the devtools package:

devtools::install_github("riccardo-df/aggTrees") # run install.packages("devtools") if needed.
