PSPP is a command-line program for statistical analysis of sampled data. It is intended as a free replacement of the proprietary program, SPSS.
It interprets commands in the SPSS language and produces output in two forms: tables and charts, and tabular output in ASCII, PostScript, or HTML format.
It already supports a large subset of SPSS’s transformation language. Its statistical procedure support is currently limited, but increasing.
- Supports over 1 billion cases.
- Supports over 1 billion variables.
- Import Excel, Gnumeric, OpenDocument spreadsheets, Comma Separated Values and ASCII files as well as Postgres databases.
- Export to SPSS ‘Portable’, ‘system’, and ASCII.
- Performs T-tests (One Sample, Independent Samples, and Paired Samples Modes), ANOVA, linear regression and other statistical operations.
- Recode, rearrange, and manipulate data.
- High-quality output formatting:
- Presentation-quality tables on suitable devices, such as laser printers and raster displays. This is currently implemented through a PostScript driver. A simple HTML tables driver is also available.
- Other devices, such as terminals and dot-matrix printers, are supported through an ASCII driver. IBM PC box-drawing characters can also be used. Bold and italics are supported if the underlying device supports them.
- Output can be directed to multiple devices at once, for instance to a dot-matrix printer and a PostScript printer, and retain the unique output properties of each device.
- Portability: PSPP is easy to port.
