Free open source statistical software links

From SPSS Wiki

While this wiki is all about SPSS, many of the contributors and users of the site look forward to a day where a reliable and adaptable [open source] [GUI] general statistical package is available to replace it. There are a number of open source solutions available for particular purposes, but the two general purpose front-runners for the title are OpenStat4 (http://www.statpages.org/miller/openstat/OS4.html) and R GUI (http://www.sciviews.org/_rgui/).

[edit] PSPP

PSPP aspires to be completely compatible with SPSS. It interprets syntax files written in the SPSS language and produces similar output. Some statistical procedures are not yet supported, but these are under development. Despite that, PSPP is in many instances a viable Free alternative to SPSS.

[edit] R (GUI Project)

R can open an SPSS file (after loading 'foreign' package) and can do more statistics than SPSS. It does have a fairly steep learning curve though.

[edit] OpenStat4
