Past 3.20 for Mac
PAST (PAlaeontological STatistics) is a data analysis package aimed at paleontology. Inspired by PALSTAT, it includes common statistical, plotting and modeling functions. It features a spreadsheet-like data entry form, and supports both interactive user interface and scripting.

This program was originally
designed as a follow-up to PALSTAT, a software package
for paleontological data analysis written by P.D. Ryan, D.A.T. Harper
and J.S. Whalley (Ryan et al. 1995).
Through continuous development for more than 15
years, PAST has grown into a comprehensive statistics package
used not only by paleontologists, but in many fields of life science, earth science, engineering and economics.
Further explanations of many of the techniques implemented together with case histories are found in the book “Paleontological data analysis” (Hammer & Harper 2005).
