From: Robert Date: 2007-09-20T04:30:12+09:00 Subject: statistical software and data transformation? How many ruby-ists have to do statistical analysis or data cleaning prior to analysis? Is it not something that is done often by web developers? What is the well known software out there for statistical software or data transformation software? That is open source, or at least free of charge? I mean besides R, I think I understand what R's strengths and limitations are. There is a number of applications at http://directory.fsf.org/math/stats/ but I do not know how mature they are (except for the one I submitted (vilno)). Is there currently a successful project for incredibly user-friendly open source statistical software, usually using a GUI, to compete with SAS (JMP) or SPSS? ( R is more for research statistics, with a tough learning curve.). Appreciate your feedback, Robert
