A Python Package for Convex Regression and Frontier Estimation

pyStoNED

pyStoNED is a Python package that provides functions for estimating multivariate convex regression, convex quantile regression, convex expectile regression, isotonic regression, stochastic nonparametric envelopment of data, and related methods. It also facilitates efficiency measurement using the conventional data envelopement analysis (DEA) and free disposable hull (FDH) approaches. The pyStoNED package allows practitioners to estimate these models in an open access environment under a GPL-3.0 License.

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.
