PSPP
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.
Features include:
- 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
