EconML: A Python Package for ML-Based Heterogeneous Treatment Effects Estimation

EconML is a Python package for estimating heterogeneous treatment effects from observational data via machine learning. This package was designed and built as part of the ALICE project at Microsoft Research with the goal to combine state-of-the-art machine learning techniques with econometrics to bring automation to complex causal inference problems. The promise of EconML:

Implement recent techniques in the literature at the intersection of econometrics and machine learning
Maintain flexibility in modeling the effect heterogeneity (via techniques such as random forests, boosting, lasso and neural nets), while preserving the causal interpretation of the learned model and often offering valid confidence intervals
Use a unified API
Build on standard Python packages for Machine Learning and Data Analysis

One of the biggest promises of machine learning is to automate decision making in a multitude of domains. At the core of many data-driven personalized decision scenarios is the estimation of heterogeneous treatment effects: what is the causal effect of an intervention on an outcome of interest for a sample with a particular set of features? In a nutshell, this toolkit is designed to measure the causal effect of some treatment variable(s) T on an outcome variable Y, controlling for a set of features X, W and how does that effect vary as a function of X. The methods implemented are applicable even with observational (non-experimental or historical) datasets. For the estimation results to have a causal interpretation, some methods assume no unobserved confounders (i.e. there is no unobserved variable not included in X, W that simultaneously has an effect on both T and Y), while others assume access to an instrument Z (i.e. an observed variable Z that has an effect on the treatment T but no direct effect on the outcome Y). Most methods provide confidence intervals and inference results.

For detailed information about the package, consult the documentation at https://econml.azurewebsites.net/.

First Stage Model Selection (click to expand)

First stage models can be selected either by passing in cross-validated models (e.g. sklearn.linear_model.LassoCV) to EconML's estimators or perform the first stage model selection outside of EconML and pass in the selected model. Unless selecting among a large set of hyperparameters, choosing first stage models externally is the preferred method due to statistical and computational advantages.

model_t = clone(cv_model).fit(W, T).best_estimator_
model_y = clone(cv_model).fit(W, Y).best_estimator_
est = LinearDML(model_y=model_t, model_t=model_y)

Inference

Whenever inference is enabled, then one can get a more structure InferenceResults object with more elaborate inference information, such as p-values and z-statistics. When the CATE model is linear and parametric, then a summary() method is also enabled. For instance:

from econml.dml import LinearDML
# Use defaults
est = LinearDML()
est.fit(Y, T, X=X, W=W)
# Get the effect inference summary, which includes the standard error, z test score, p value, and confidence interval given each sample X[i]
est.effect_inference(X_test).summary_frame(alpha=0.05, value=0, decimals=3)
# Get the population summary for the entire sample X
est.effect_inference(X_test).population_summary(alpha=0.1, value=0, decimals=3, tol=0.001)
#  Get the parameter inference summary for the final model
est.summary()

Example Output (click to expand)

# Get the effect inference summary, which includes the standard error, z test score, p value, and confidence interval given each sample X[i]
est.effect_inference(X_test).summary_frame(alpha=0.05, value=0, decimals=3)

# Get the population summary for the entire sample X
est.effect_inference(X_test).population_summary(alpha=0.1, value=0, decimals=3, tol=0.001)

#  Get the parameter inference summary for the final model
est.summary()

Policy Learning

You can also perform direct policy learning from observational data, using the doubly robust method for offline policy learning. These methods directly predict a recommended treatment, without internally fitting an explicit model of the conditional average treatment effect.

Doubly Robust Policy Learning (click to expand)

from econml.policy import DRPolicyTree, DRPolicyForest
from sklearn.ensemble import RandomForestRegressor

# fit a single binary decision tree policy
policy = DRPolicyTree(max_depth=1, min_impurity_decrease=0.01, honest=True)
policy.fit(y, T, X=X, W=W)
# predict the recommended treatment
recommended_T = policy.predict(X)
# plot the binary decision tree
plt.figure(figsize=(10,5))
policy.plot()
# get feature importances
importances = policy.feature_importances_

# fit a binary decision forest
policy = DRPolicyForest(max_depth=1, min_impurity_decrease=0.01, honest=True)
policy.fit(y, T, X=X, W=W)
# predict the recommended treatment
recommended_T = policy.predict(X)
# plot the first tree in the ensemble
plt.figure(figsize=(10,5))
policy.plot(0)
# get feature importances
importances = policy.feature_importances_

For Developers

You can get started by cloning this repository. We use setuptools for building and distributing our package. We rely on some recent features of setuptools, so make sure to upgrade to a recent version with pip install setuptools --upgrade. Then from your local copy of the repository you can run pip install -e . to get started (but depending on what you're doing you might want to install with extras instead, like pip install -e .[plt] if you want to use matplotlib integration, or you can use pip install -e .[all] to include all extras).

Running the tests

This project uses pytest for testing. To run tests locally after installing the package, you can use pip install pytest-runner followed by python setup.py pytest.

We have added pytest marks to some tests to make it easier to run a subset, and you can set the PYTEST_ADDOPTS environment variable to take advantage of this. For instance, you can set it to -m "not (notebook or automl)" to skip notebook and automl tests that have some additional dependencies.

Generating the documentation

This project's documentation is generated via Sphinx. Note that we use graphviz's dot application to produce some of the images in our documentation, so you should make sure that dot is installed and in your path.

To generate a local copy of the documentation from a clone of this repository, just run python setup.py build_sphinx -W -E -a, which will build the documentation and place it under the build/sphinx/html path.

The reStructuredText files that make up the documentation are stored in the docs directory; module documentation is automatically generated by the Sphinx build process.

Release process

We use GitHub Actions to build and publish the package and documentation. To create a new release, an admin should perform the following steps:

Update the version number in econml/_version.py and add a mention of the new version in the news section of this file and commit the changes.
Manually run the publish_package.yml workflow to build and publish the package to PyPI.
Manually run the publish_docs.yml workflow to build and publish the documentation.
Under https://github.com/py-why/EconML/releases, create a new release with a corresponding tag, and update the release notes.

Contributing and Feedback

This project welcomes contributions and suggestions. We use the DCO bot to enforce a Developer Certificate of Origin which requires users to sign-off on their commits. This is a simple way to certify that you wrote or otherwise have the right to submit the code you are contributing to the project. Git provides a -s command line option to include this automatically when you commit via git commit.

When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate the PR appropriately (e.g., label, comment). Simply follow the instructions provided by the bot. You will only need to do this once across all repos using our CLA.

This project has adopted the PyWhy Code of Conduct.

Community

EconML is a part of PyWhy, an organization with a mission to build an open-source ecosystem for causal machine learning.

PyWhy also has a Discord, which serves as a space for like-minded casual machine learning researchers and practitioners of all experience levels to come together to ask and answer questions, discuss new features, and share ideas.

We invite you to join us at regular office hours and community calls in the Discord.
