Genstat is a general statistical package. Early versions were developed for large mainframe computers. Up until version 5 (released 1987), there was a Unix binary available, and this continues to be used by many universities and research institutions. Later versions are available for the Windows environment only.
Genstat Discovery Edition is a free version of the statistical software Genstat. Genstat Discovery Edition 3 is available to non-commercial users throughout Africa and a range of developing countries outside Africa. Examples of users who qualify are students and lecturers of universities and staff of government research organisations or NGOs. When you register for a license you will be asked for information about the status of the organisation which will be using the software to determine whether it qualifies for the free version.
