This is an efficient implementation of Friedman's SuperSmoother [1] algorithm in pure Python. It makes use of numpy for fast numerical computation.
Installation is simple: To install the released version, type
$ pip install supersmootherTo install the bleeding-edge source, download the source code from http://github.com/jakevdp/supersmoother and type:
$ python setup.py installThe only package dependency is numpy; scipy is also required if you want to run the unit tests.
The package includes several example notebooks showing the code in action.
You can see these in the examples/ directory, or view them statically
on nbviewer
This code has full unit tests implemented in nose. With nose installed, you can run the test suite using
$ nosetests supersmootherThe package is tested with Python versions 2.7, 3.4, 3.5, and 3.6.
supersmoother was created by Jake VanderPlas
