We develop tools for applied (micro-) econometrics in Python.
-
pyfixest implements fast routines for fixed effects regression (OLS, IV, Poisson) and a wide range of inference procedures (iid, HC1-3, CRV1, CRV3, randomization inference, multiple testing corrections via Bonferroni & Romano-Wolf) following the syntax of the formidable fixest R package.
-
duckreg provides a simple interface to run lossless regressions on very large datasets that do not fit in memory by first reducing the data to a set of summary statistics out-of-memory using duckdb and then running weighted least squares with frequency weights.
-
wildboottest implements multiple fast wild cluster bootstrap algorithms as developed in Roodman et al (2019) and MacKinnon, Nielsen & Webb(2022).
-
fastmatch implements fast matching estimators for causal inference that uses faiss for nearest neighbours.
-
gmm helps you minimize generalized methods of moments (GMM) objective functions.
