The R package DoubleML provides an implementation of the double / debiased machine learning framework of Chernozhukov et al. (2018). It is built on top of mlr3 and the mlr3 ecosystem (Lang et al., 2019).
Note that the R package was developed together with a python twin based
on scikit-learn. The python package is also
available on GitHub and

Double / debiased machine learning framework of Chernozhukov et al. (2018) for
- Partially linear regression models (PLR)
- Partially linear IV regression models (PLIV)
- Interactive regression models (IRM)
- Interactive IV regression models (IIVM)
The object-oriented implementation of DoubleML that is based on the
R6 package for R is very flexible. The model
classes DoubleMLPLR, DoubleMLPLIV, DoubleMLIRM and DoubleIIVM
implement the estimation of the nuisance functions via machine learning
methods and the computation of the Neyman orthogonal score function. All
other functionalities are implemented in the abstract base class
DoubleML. In particular functionalities to estimate double machine
learning models and to perform statistical inference via the methods
fit, bootstrap, confint, p_adjust and tune. This
object-oriented implementation allows a high flexibility for the model
specification in terms of …
- … the machine learning methods for estimation of the nuisance functions,
- … the resampling schemes,
- … the double machine learning algorithm,
- … the Neyman orthogonal score functions,
- …
It further can be readily extended with regards to
- … new model classes that come with Neyman orthogonal score functions being linear in the target parameter,
- … alternative score functions via callables,
- … alternative resampling schemes,
- …
