A Package for Stochastic Nonparametric Envelopment of Data (StoNED) in Python
Project description
pyStoNED 
pyStoNED is a Python package that provides functions for estimating Convex Nonparametric Least Square (CNLS), Stochastic Nonparametric Envelopment of Data (StoNED), and other various StoNED-related variants (e.g., CQR, ICNLS). It allows the user to estimate the CNLS/StoNED models in an open-access environment rather than in commercial software, e.g., GAMS, MATLAB. The pyStoNED package is built based on the PYOMO.
Installation
The pyStoNED package is now avaiable on PyPI and the latest development version can be installed from the Github repository pyStoNED. Please feel free to download and test it. We welcome any bug reports and feedback.
PyPI
