Patsy
Notice: patsy is no longer under active development. As of August 2021,
Matthew Wardrop (@matthewwardrop) and TomΓ‘s Capretto (@tomicapretto) have taken
on responsibility from Nathaniel Smith (@njsmith) for keeping the lights on, but
no new feature development is planned. The spiritual successor of this project
is Formulaic, and we
recommend those interested in new feature development contribute there. Those
whose use-cases continue to be met by patsy can continue using this package
with increased confidence that things will continue to work as is for the
foreseeable future.
Patsy is a Python library for describing statistical models (especially linear models, or models that have a linear component) and building design matrices. Patsy brings the convenience of R "formulas" to Python.
