Finding an appropriate statistics package
You can find lists of useful statistics and analysis software in places like:
- Free Statistical Software
- Open Statistics
- Free Resources for Program Evaluation and Social Research Methods
- http://en.citizendium.org/wiki/Free_statistical_software
Many are very specialised, some will work on some platforms but not others, some are genuinely open source, others are not, and so on. SOFA Statistics has been developed because there is a gap in the market for an open source, easy-to-use Statistics Package with an emphasis on the most common tests, and on producing beautiful output.
