Projects

All Software

Deautils

This repository will host various utilities that one may need when doing Data Envelopment Analysis (DEA).

matlabutils

I keep a repository with useful MATLAB utility functions that intend to make MATLAB programming just that more easy.

nepa

Nonparametric Efficiency and Productivity Analysis for Julia. A toolbox for doing efficiency analysis and computing productivity change using nonparametric techniques.

nprlab

NonParametric Regression Laboratory for MATLAB (NPRLab) is a MATLAB toolbox for nonparametric regression. In particular, it implements a variety of linear estimators. Data rescaling and bandwidth tuning is done automatically by the software. Finally, the toolbox also features confidence interval estimation by the volume-of-tube formula both in a one-dimensional and multi-dimensional setting.

Teaching
