- The econometrics toolbox consists of MatLab routines, written by James LeSage, with contributions by others. For those comfortable with MatLab, LeSage's toolbox has become an excellent choice, particularly when working with models with very large numbers of observations (a consideration that doesn't apply to the SCCS). One caution: the toolbox works only with MatLab, and not with open-source clones such as GNU Octave, or the MatLab emulator on R.
- GeoDa is a user-friendly package with an attractive GUI, including maps, developed by Luc Anselin and his collaborators. GeoDa is emerging as a popular choice for researchers who prefer a point-and-click GUI.
