Welcome! Data Envelopment Analysis (DEA) is a family of methods for efficiency measurement. This page contains some software related links, datasets, and information about my research. For general information about DEA you may have a look at the following DEA WWW pages:

Tim Anderson's DEA page, contains a short introduction to DEA.
Ali Emrouznejad's DEA HomePage, very comprehensive.
Laura's page, includes stochastic frontiers.
Gabriel Tavares' DEA home page, with DEA bibliography.
Euro-DEAPM, the working group of the European OR societies.

Many mathematical modeling systems are prepared for DEA:

LINGO solves CCR model.
For GAMS there is a free DEA code by Olesen/Petersen at PARN, described in Computers Ops Res. 23 (1996), pp. 323-339.
