Statistical Packages

Statistical packages let people analyse data - e.g. to see if there is a difference in the average vocabulary size of males vs females. There are many statistics programs available. Many are very specialised, some will work on some platforms but not others (e.g. Windows only), some are genuinely open source, others are not, some are very expensive and some are free, and so on. This site promotes free and open source statistical packages.

Advantages of Free and Open Source Packages

"Open" means:
  1. No crippleware - all users get the full power available
    Students etc can use full versions of open source software, not deliberately crippled versions.

  2. Freedom and convenience
    No dongles etc - easy to install on your work machine, laptop, Asus EEE, Ubuntu box etc. Can keep up with the latest version without ongoing payments.

  3. Legitimacy and openness
    Many people use pirated versions because they are unable to afford the prices of the proprietary vendors (e.g. students or people in the developing world). With open statistics it is possible to enter fully into the community of the software you use - using, contributing, providing support etc.

  4. Transparent and auditable analysis
    Can you ever really trust what you can't see?

  5. People can learn from open algorithms and experts can contribute to them
    There are some very smart people out there and we can all benefit from their contributions.

  6. Give citizen-activists the tools needed to promote open democracy (e.g. Open New Zealand)
    Open society requires open data and analysis tools. Investigative journalism is withering up so citizens need direct access to government data and the tools to analyse it themselves. We can't rely on the media to expose flaws in government policy.
