After having difficulty getting PSPP to work on a Mac I contacted the gentleman who hosts the program (an apparently updates the files) and informed him of the issues I was encountering. It took a few weeks, but he updated the download file. Mac build now supports Vulkan on top of MoltenVK (#12583) Raspberry Pi 4 EGL crash fixed (#12474) VSync now supported on all backends, frame duplication option added for 30 Hz games (#12659, #12602) Camera supported on Windows, Linux and Mac (still no microphone though) (#12572, #12580, #12607) Darkstalkers fixed and working through software.

- About PSPP for Mac. PSPP is a Free program for statistical analysis of sampled data. It is a replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. Statisticians, students and scientists find it an ideal tool for convenient and fast sample data analysis. Further information can be found at the PSPP.
- One of the reasons why it was a big hit is the major graphics improvements and raw power. The unit was able to push more advanced games and to be used as a device that can play movies, play music and surf the web. It is also able to connect to PS2 and 3 and any computer running Mac OS or Windows.
GNU PSPP — Frequently Asked Questions
Here we try to answer some of the questions about PSPP that arise from time to time.
What is PSPP?
PSPP is a program for statistical analysis of sampled data. Itis a free replacement for the proprietary program, SPSS.
One goal of the PSPP project is compatibility with the SPSSlanguage. It currently features:
- High-quality output formatting.
- An easy to use graphical user interface.
- A command line interface to allow seasoned users to rapidly perform analysis.
- A comprehensive selection of data preprocessing, analysis and visualisation commands.
- Portability: PSPP can be built on a very wide range of platforms.
What can PSPP do?
PSPP provides many transformations and utilities. Procedures provide the ability to perform t-tests, anova, linear regression,logistic regression, cluster analysis,reliability analysis, factor analysis, non parametric tests and other analyses.
Refer to the manual for the completelist of supported commands.
Where can I get PSPP?
See this page.
How do I install PSPP?
There are several methods:
- Many operating systems come with PSPP already packaged. This is often the easiest method, but might not get you the most up to date version. An incomplete list of packages for various operating systems.
- Download a tarball and follow the instructions in theINSTALL file.This is the canonical method used for most GNU software.
- However, if really want the very latest version, and are willing to put in extra effort to install it, and are prepared to accept that it may contain bugs, then compile from the Git snapshot. Look in the fileREADME.GIT file and follow the instructions there.
How do I get started using PSPP?
Having installed PSPP, try this:
- Using your favourite editor, write a file (name it myfile.sps) containing the following:
- Enter the command pspp myfile.sps
- Look at your results in pspp.list
PSPP is very versatile and there are lots of different types ofstatistical analysis possible. You need to become familiar with thedocumentation to unleash its full potential.
How do I configure the PSPP interface language?
PSPP respects the locale of the environment. So if, for example, youroperating system (or the currently logged in user) is set toPortuguese, then that is what PSPP will display.
How you change the environment's locale depends on the operatingsystem. For example, on GNU or on GNU/Linux you could use the command
export LANG=pt_PT
(for Portuguese spoken in Portugal)or export LANG=pt_BR
for Brazillian Portuguese. Thisshould also work for all operating systems which are POSIX compliant.For others, you will have to refer to your OS documentation.What documentation is available?
The PSPP manual,written in Texinfo format, is the primary reference for using PSPP.Besides the Texinfo format a few other formats are available like HTML and PDF. A fewadditional documentation files are included in the source distribution:
- README
- A quick introduction to PSPP.
- INSTALL
- Notes on building and installing.
- ChangeLog
- Details of the latest bleeding edge changes.
A manual for PSPP in French, written independently by Julie Séguéla, is alsoavailable in PDFand LaTeXformats.
A guide to PSPP in Polish, written independently by Daniel Mider and AnetaMarcinkowska, is also available.
There are also heaps of unofficial resources on the internet.Use a search engine to find them.
There are a lot of concepts I don't understand. Where can I learn about them?

Lane, Rice University.Disclaimer: PSPP, its developers and the GNU Project have no affiliation with this publisher or author of this book.
PSPP is a clone of SPSS. So why should I use PSPP when SPSS has all the same features?
Firstly, PSPP is not a 'clone'. No part of SPSS was used to write PSPP and there is no code shared between the projects. If it was a clone, then therewould indeed be no advantage using one program or the other.But instead, PSPP is an independent free software program (and one of its design goals was ease of use for people already familiar with SPSS).
Among other advantages, this means that if you find it doesn't completelyfit your needs - perhaps there is a statistical test which you would like itto perform - then you have the means and the right to improve it to fit your requirements. Whereas if you attempted to do this with non-free software such as SPSS it would be both difficult and illegal.
Furthermore, because PSPP is free software, you can use it for whatever you like and for as long as you like (there's no 'expiry') and you are welcome to give away (or sell) copies to others - for example to students undertaking anintroductory statistics course. If you have made your own improvements, then you can include those changes in the copies you distribute.
Another important advantage: Since the source code is available to all, unlimited peer review is possible. Should PSPP's accuracy be called intoquestion, it can easily be audited by a competent, independent authority.Conversely, since the source code of proprietary software is secret, nobodycan check to see if it contains numerical instability, inappropriate algorithm implementations or other potential errors.
Some secondary reasons why people sometimes prefer PSPP include:
- Reduced costs
- Inter platform portability
- A number of people have reported that PSPP runs faster
- Features not available in other software, such as importing from Postgres, Gnumeric etc.
- It comes already bundled with popular operating systems, such as Debian GNU/Linux
How can I be sure that PSPP gives accurate results?
When you install PSPP, the GNU Project gives you exactly the same warranty that you would get with any proprietary program viz:None at all.
However, we feel confident that PSPP provides reliable and accurate results for a number or reasons
- Every release has over 1000 tests. These are run before each release. In addition, you can run them on your own machine to make sure PSPP is accurate for your platform.
- For many years there has been a publicly available bug reporting and tracking service, where anyone can report problems. Many issues have been brought to our attention but there have been few, if any, confirmed reports of a miscalculated statistic on a released PSPP version.
- We regularly analyse the code using tools such as valgrind and gcov to expose any latent defects.
- The complete source code is available for everyone to review which, should bugs be inadvertently introduced, increases the chances of them being quickly discovered and fixed.
As already mentioned, the Free Software Foundation does not provide any warranty for PSPP.However, unlike with proprietary software, you are free to engage any third party of your choiceto provide a support contract and/or a warranty service with terms acceptable to you.
Can I use PSPP at school/college/university?
Many introductory statistics courses specify the use of some statistical analysis software.Some schools specify or recommend the use of PSPP.Others will permit its use if the student asks.If you are enrolled in a course which specifies a proprietary statistical analysis program,we would encourage you to speak to the coordinator of the course and explain that you would prefer to use a free software package (such as PSPP) instead.Today, many schools and universities have a formal policy that students must not be compelledto use proprietary software when an alternative exists.It is worth finding out if this is the case at your institution.Speak to your students' association if necessary.
Are PSPP's results accepted for publication in scientific papers?
What is and is not accepted for publication in a journal is up to that journal's editor. We are not aware of any paper ever having been rejected on the grounds that PSPP was used, but we are aware of studies using PSPP for analysis, which have been published by reputable academic journals.
Please also be aware of PSPP's warranty.
I get an error message: 'Number followed by garbage' and my data is blank.
This warning means that you are trying to import data using
DATA LIST
and the dataencountered does not match the format you have specified. Check that there are no straycharacters in the data.How To Download Pspp
If you are running under a non English locale and you are importing decimal data, it islikely that you have data with dots as decimal separators whereas PSPP is expectingcommas. Either change the dots to commas, or place the line
SET DECIMAL DOT.
atthe top of the file.Results are displayed only to 2 decimal places. I need more.
At the top of your syntax file, or in your .pspprc file, put (for example) the line
SET FORMAT F22.6.
which will tell PSPP to print all results to 6 decimal placesand to a formatted width of 22 columns.I have my data in a spreadsheet. How can I import it into PSPP?
PSPP can directly import spreadsheets created by Gnumeric, LibreOffice and Openoffice.Org. To do so, use the
GET DATA
command. Alternatively, if using the GUI, click on 'File|Import Data'.We recommend you convert all your spreadsheets either to Gnumeric or Libreoffice format to avoid this extra step.If you have the proprietary spreadsheet program MSExcel you can do this in one of the following ways:
- First save the data as Comma Separated Values (csv) and import it into the free spreadsheet program
- Some versions of Excel allow you to save the data directly as an Open Document Spreadsheet (ods) file
- We encourage everyone to use free software applications. If however for some reason you want to continue using MSOffice you can set default file format to OpenDocumentFormat
Can PSPP open encrypted .sav
or .sps
files?
PSPP includes a tool, named
pspp-convert
, that can decrypt encrypted .sav
or .sps
files, given the password. Please read the PSPP manual or the pspp-convert
manual, for details. The SPSS encrypted syntax file format is unacceptably insecure, so to discourage its use PSPP and PSPPIRE do not directly read or write this file format.
How can I get more information on PSPP?
There are several resources for PSPP information. The first is this FAQ andrelated documentation in the distribution and on the web site. The second isthe PSPP source code itself, if you are programmatically inclined.
For discussion with other PSPP users our mailinglist [email protected] is available. You can subscribe to this list at http://lists.gnu.org/mailman/listinfo/pspp-users
Finally, we look forward to all comments and questions related to PSPP.The irc channel is #pspp, which is on the freenode network.
Why don't you merge PSPP with R, GRETL, Octave ... <my favourite program>?
This suggestion comes up from time to time. It is unlikely to happen for anumber of technical, philosophical and legal reasons.
However, we certainly want to provide features which will make PSPPeasier to interact with other programs.If you want an import/export filter or some other feature to help PSPPcomplement your favourite program, then please talk to us about it.
PSPP lacks this feature which I really need. How can I get PSPP tosupport it?
There are several ways:
- Download the source code and implement it yourself.
- Hire somebody to implement it for you.
- Send an email to the developers and ask for the feature. The developers are interested in hearing about what users want.
Any help you can give is appreciated. See the following question.
Can I help out with PSPP development?
Yes. We will gladly accept help in the form of improvements to the code, artwork or documentation.
When you have fixed a bug or improved some parts of PSPP, you cansubmit your patches at http://savannah.gnu.org/patch/?group=pspp
Sometimes users wish to contribute money toward PSPP development. The PSPP developers appreciate the spirit behind this idea, but monetary donations are less useful than other forms of help.
Something doesn't work properly on Windows/Mac.
Pspp Statistical software, free download
PSPP is GNU Software and part ofthe GNU System.That means the platforms under which it works best are GNU andGNU/Linux.Like all GNU software, cross platform portability is something which we try to achieve,but it is not the highest priority.Furthermore, supporting free systems takes precedenceover non-free platforms, such as windows or Mac OS,and as a matter of policy PSPP will always work best on a free operating system.
To sum up: Windows and Mac are low on our list of priorities. We recommend youswitch to a free operating system. Bug fixes however,are always accepted.
What does PSPP stand for?
PSPP does not have any official acronymic expansion. But they're easy tocome up with. For example:
- Perfect Statistics Professionally Presented.
- Probabilities Sometimes Prevent Problems.
- People Should Prefer PSPP.

GNU PSPP
PSPP 1.4.1 has been released.
GNU PSPP is a program for statistical analysis of sampled data. It is a free as in freedomreplacement for the proprietary program SPSS, and appears very similar to it with a few exceptions.
The 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 onthe 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 is a stable and reliable application. It can perform descriptive statistics, T-tests, anova, linear and logistic regression,measures of association, cluster analysis, reliability and factor analysis, non-parametric tests and more.Its backend is designed to perform its analyses as fast as possible, regardlessof 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 PSPP's features follows below.We also made available a page with screenshots and sample output.PSPP has:
- Support for over 1 billion cases.
- Support for over 1 billion variables.
- Syntax and data files which are compatible with those of SPSS.
- A choice of terminal or graphical user interface.
- A choice of text, postscript, pdf, opendocument or html output formats.
- Inter-operability with Gnumeric, LibreOffice, OpenOffice.Org and other free software.
- Easy data import from spreadsheets, text files and database sources.
- The capability to open, analyse and edit two or more datasets concurrently. They can also be merged, joined or concatenated.
- A user interface supporting all common character sets and which has been translated to multiple languages.
- Fast statistical procedures, even on very large data sets.
- No license fees.
- No expiration period.
- No unethical “end user license agreements”.
- A fully indexed user manual.
- Freedom ensured; It is licensed under the GPLv3 or later.
- Portability; 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.
Downloading PSPP
As with most GNU software, PSPP can be found on the main GNU ftp server:http://ftp.gnu.org/gnu/pspp/(via HTTP) andftp://ftp.gnu.org/gnu/pspp/(via FTP). It can also be foundon the GNU mirrors;pleaseusea mirror if possible.
There are some additional ways youcan download or otherwise obtain PSPP.
Documentation
Documentation forPSPPis available online, asis documentation for most GNU software. You mayalso find more information aboutPSPPby runninginfo pspporman pspp,or by looking at/usr/share/doc/pspp/,/usr/local/doc/pspp/,or similar directories on your system. A brief summary is available byrunning pspp --help.
