PSPP is a program for statistical analysis of sampled data. It is a free replacement for the proprietary program, SPSS.
One goal of the PSPP project is compatibility with the SPSS language. It currently features:i
- 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.
- All this can be done on any operating system that PSPP supports. Though the latest versions of what PSPP replaces support similar functionality, they do so only under non-free Microsoft operating systems.
- Portability: PSPP is easy to port. It should be simple to port it to any POSIX.1 compliant operating system having an ANSI C compiler.
