GNU PSPP

GNU PSPP is an application designed for the statistical analysis of sampled data, providing data management and analytical procedures. It features a user interface that combines a spreadsheet-like data sheet with a syntax execution window, allowing users to run commands either through menu selections or by writing batch scripts. The program handles large datasets, performs descriptive statistics, linear regression, ANOVA, and non-parametric tests, and generates textual or graphical output.

Built for Linux platforms, PSPP reads and writes data files in standard formats, enabling compatibility with existing research workflows. It processes commands sequentially and provides logs of statistical output for review and export. The software focuses on numerical computations and data manipulation without relying on proprietary statistical suites.
