causarray is a Python module for simultaneous causal inference with an array of outcomes.
Project description
causarray
Advances in single-cell sequencing and CRISPR technologies have enabled detailed case-control comparisons and experimental perturbations at single-cell resolution. However, uncovering causal relationships in observational genomic data remains challenging due to selection bias and inadequate adjustment for unmeasured confounders, particularly in heterogeneous datasets. To address these challenges, we introduce causarray [Du25], a doubly robust causal inference framework for analyzing array-based genomic data at both bulk-cell and single-cell levels. causarray integrates a generalized confounder adjustment method to account for unmeasured confounders and employs semiparametric inference with flexible machine learning techniques to ensure robust statistical estimation of treatment effects.
Usage
We recommend using causarray in a conda environment:
# create a new conda environment and install the necessary packages
conda create -n causarray python=3.12 -y
# activate the environment
conda activate causarray
The module can be installed via PyPI:
pip install causarray
For R users, reticulate can be used to call causarray from R.
The documentation and tutorials using both Python and R are available at causarray.readthedocs.io.
