Included in the distribution are real data sets for educational use, together with extensive documentation and case studies.

PAST has been tested under Windows XP, Vista and Windows 7.

PAST (abgeleitet aus PAlaeontological STatistics) ist ein kompaktes Datenanalyseprogramm, welches trotzdem alle wesentlichen Funktionen mit sich bringt. Neben dem Programm sind Testdaten, Dokumentation und Fallstudien als Beispiel enthalten, um den Zugang zu erleichtern.
