1 Introduction

pspp is a tool for statistical analysis of sampled data. It reads a syntax file and a data file, analyzes the data, and writes the results to a listing file or to standard output.

The language accepted by pspp is similar to those accepted by SPSS statistical products. The details of pspp's language are given later in this manual.

pspp produces tables and charts as output, which it can produce in several formats; currently, ASCII, PostScript, PDF, HTML, and SVG are supported.

The current version of pspp, 0.7.9, is woefully incomplete in terms of its statistical procedure support. pspp is a work in progress. The author hopes to fully support all features in the products that pspp replaces, eventually. The author welcomes questions, comments, donations, and code submissions.
