There was a download of PPStat 3.50 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The program's installer file is generally known as PPSTAT.EXE. The most popular versions among the program users are 3.5 and 0.4.
The software lies within Education Tools, more precisely Science Tools. This free software was originally designed by Niels Richard Hansen. The latest version of the software can be installed on PCs running Windows XP/Vista/7/8/10/11, 32-bit. We recommend checking the downloaded files with any free antivirus.
From the developer:
The R-package ppstat implements methods for point process statistics for multivariate point processes (that is, marked point processes) on the line. The package is still under development.
The package is based on another R-package processdata. This package implements a data structure for storing point process and general stochastic process data. It includes various plotting and subsetting facilities.
