Besides the legal issues here I would recommend R. R, also known as "GNU S", is a language and environment for statistical computing and graphics. R implements a dialect of the award-winning language S, developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, ...). R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs out of the box on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux). It also compiles and runs on Windows 9x/NT/2000 (for which it can also be obtained as pre-compiled binary).
