GNU PSPP
What it is
GNU PSPP is a free desktop program for statistical analysis of sampled data and a free replacement for SPSS. It offers both graphical and command-line interfaces, with analyses including descriptive statistics, t-tests, ANOVA, linear and logistic regression, cluster analysis, reliability and factor analysis, and non-parametric tests. Its syntax and data files are compatible with SPSS, and the project aims to produce similar results. PSPP can import PSPP system and portable files, Gnumeric, ODS, PostgreSQL, and TXT or other delimited text. Results can be output as text, PostScript, PDF, OpenDocument, or HTML. The project also lists interoperability with Gnumeric, LibreOffice, OpenOffice.org, and other free software. PSPP supports scripting and is licensed under the GNU GPL version 3 or later. Its listed plan is free, with no license fees and no artificial limits on cases or variables. The manual describes statistical procedure support as incomplete and a work in progress. The project particularly aims to serve statisticians, social scientists, and students analyzing sampled data.
For and against
For
- Graphical and command-line interfaces are available.
- Supports regression, tests, and other statistical analyses.
- Imports spreadsheet, database, and text data.
- Exports results to PDF, HTML, and other formats.
- No license fees or artificial case and variable limits.
Against
- Statistical procedure support is incomplete.
- Developers cannot promise immediate responses to bug reports.
The verdict
PSPP covers a broad set of statistical analyses and supports both graphical and command-line work. Its manual cautions that procedure support remains incomplete, which may matter for users who need a particular analysis.
Who it suits
PSPP may suit statisticians, social scientists, and students working with sampled data. It is also relevant to users who want a free desktop tool with SPSS-compatible syntax and data files.
