bartcs: Bayesian Additive Regression Trees for Confounder Selection

Description

Fit Bayesian Regression Additive Trees (BART) models to select true confounders from a large set of potential confounders and to estimate average treatment effect. For more information, see Kim et al. (2023) doi:10.1111/biom.13833.

Details

Functions in bartcs serve one of three purposes.

1. Functions for fitting: separate_bart() and single_bart().

2. Functions for summary: summary() and plot().

3. Utility function for OpenMP: count_omp_thread().

The code of BART model are based on the 'BART' package by Sparapani et al. (2021) under the GPL license, with modifications. The modifications from the BART package include (but are not limited to):

• Add CHANGE step.

• Add Single and Separate Model.

• Add causal effect estimation.

• Add confounder selection.
