Complex application for analyzing scientific data in the form of statistics which draws graphs and plots with an interface similar to other spreadsheet software.
PAST is a freeware data analyzer app and calculator developed by Oyvind Hammer for Windows. It's well-designed, light on system resources, advanced and powerful.
The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of PAST to illustrate the user interface and show the overall usage and features of this data analyzing program.
Spreadsheet-style software for scientific analysis of data and numbers
Past is free software for scientific data analysis, with functions for data manipulation, plotting, univariate and multivariate statistics, ecological analysis, time series and spatial analysis, morphometrics and stratigraphy.

Compatibility and License
PAST is provided under a freeware license on Windows from calculators with no restrictions on usage. Download and installation of this PC software is free and 4.03 is the latest version last time we checked.
What version of Windows can PAST run on?
PAST can be used on a computer running Windows 11 or Windows 10. Previous versions of the OS shouldn't be a problem with Windows 8 and Windows 7 having been tested. It's only available as a 64-bit download.
