PSPP is a program for statistical analysis of sampled data. It is a Free
replacement for the proprietary program SPSS, and appears very similar to
it with a few exceptions.
he most important of these exceptions are, that there are no “time bombs”;
your copy of PSPP will not “expire” or deliberately stop working in the future.
Neither are there any artificial limits on the number of cases or variables
which you can use. There are no additional packages to purchase in order
to get “advanced” functions; all functionality that PSPP currently supports is
in the core package.
PSPP can perform descriptive statistics, T-tests, anova, linear and logistic
regression, cluster analysis, factor analysis, non-parametric tests and more.
Its backend is designed to perform its analyses as fast as possible,
regardless of the size of the input data. You can use PSPP with its graphical
interface or the more traditional syntax commands.
A brief list of some of the features of PSPP follows:
Supports over 1 billion cases.
Supports over 1 billion variables.
Syntax and data files are compatible with those of SPSS.
Choice of terminal or graphical user interface.
Choice of text, postscript, pdf, opendocument or html output formats.
Inter-operates with Gnumeric, LibreOffice, OpenOffice.Org and other free
Easy data import from spreadsheets, text files and database sources.
User interface supports all character sets and has been translated to multiple
Fast statistical procedures, even on very large data sets.
No license fees.
No expiration period.
No unethical “end user license agreements”.
Fully indexed user manual.
Free Software; licensed under GPLv3 or later.
Cross platform; Runs on many different computers and many different
operating systems (GNU or GNU/Linux are the prefered platforms, but we have
had many reports that it runs well on other systems too).
PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient
analysis of sampled data.
