Past v3.22 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).

Complete PDF manual here.

Past works under Windows 7, Windows 10, and Mac OSX.


New option in cluster analysis: Constrain clustering to given groups, and collapse clusters to the groups.
Common Allometric Components analysis for 2D landmarks
Function to fill cells with value (useful for several things)
Symbol size can now be set to 0, allowing only convex hulls or concentration ellipses to be plotted, not the individual points
Graph plot now allows plotting also by rows, not only columns
Pie chart, stacked chart, radar chart: Treatment of missing values improved.
Column widths, if changed by user, are now saved with the Past file.
Text export of concentration ellipse parameters
Bug fix: Standard error on the intercept in RMA and MA bivariate regression was incorrect
Bug fix: Excessive line width of concentration ellipses in exported PDF
Bug fix: Export of degenerate (zero-size) concentration ellipses to PDF gave warning message in Acrobat Reader
Bug fix: Summary statistics, calculation of 25th and 75th percentiles failed for N<4
Bug fix: Two-way PERMANOVA crashed for data sets with more than ca. 10,000 columns
