PSPP 1.4.0 has been released

I'm very pleased to announce the release of a new version of GNU PSPP.  PSPP is a program for statistical analysis of sampled data.  It is a free replacement for the proprietary program SPSS.

Changes from 1.2.0 to 1.4.0:

  • The file pspp-mode.el (the pspp-mode for Emacs) is no longer distributed with PSPP.  Instead, it can be installed directly in emacs and is available from
  • The Find dialog box, when searching for numeric values, will match only to the precision of the variable's print format.  This avoids behaviour which is suprising to some users.
  • PSPP now supports the SPSS viewer (.spv) format that SPSS 16 and later use to save the contents of its output editor:
    • PSPP and PSPPIRE can write output to .spv files.
    • The new utility pspp-output can convert .spv files to other formats.
    • The pspp-convert utility can now decrypt encrypted .spv files.  The encrypted viewer file format is unacceptably insecure, so to discourage its use PSPP and PSPPIRE do not directly read or write this format.
  • A bug where the Data|Select Cases|Random Sample menu would generate invalid syntax has been fixed.
  • FREQUENCIES will emit a warning if one or more weight values are missing.
  • Plain text output is no longer divided into pages, since it is now rarely printed on paper.
  • pspp-convert improvements:
    • New "-a", "-l", "--password-list" options to search for an encrypted file's password.
    • New "--keep" and "--drop" options to output only selected variables.
    • New "--recode", "--no-var-name", "--labels", "--print-formats", "--decimal", "--delimiter", and "--qualifier" options to control CSV output.
  • Improvements to SAVE DATA COLLECTION support for MDD files.
  • Bug fix for CVE-2018-20230.
  • The /RENAME subcommand in SAVE TRANSLATE et al. has been extended to support the syntax also accepted by other software.
  • The EXAMINE command will now perform the Shapiro-Wilk test when one or more plots are requested.
  • The REGRESSION command now supports the /STATISTICS=TOL option which outputs tolerance and variance inflation factor metrics for the data.
  • The QUICK CLUSTER command now supports the /SAVE option which can be used to save the cases' cluster membership and/or their distance from the cluster centre to the active file.
  • The MEANS command has been re-implemented.
  • The GUI now has a sub-dialog for post-hoc tests of the oneway anova test.
  • Gtk+3.22.0 or later must now be used when building.
  • GRAPH: Categorical barcharts displaying percentages now show the sub-category as a percentage of the primary category instead of the total.
  • The Syntax Window now has a Find function to perform simple text searching.
    • The PRINT subcommand is now implemented.
    • Many bug fixes.
