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 1.4.1 to 1.6.0:

  • In the Kruskal-Wallis test, a misleading result could occur if the lower bound specified by the user was in fact higher than the upper bound specified.  This has been fixed.
  • The DEFINE, MATRIX, MCONVERT, and MATRIX DATA commands are now implemented.
  • An error in the displayed signficance of oneway anova contrasts tests has been corrected.
  • Added Drag-N-Drop in output view.
  • The Explore GUI dialog supports the "Plots" subdialog. Boxplots, Q-Q Plots and Spreadlevel plots are now also available via the GUI.
  • The graphical user interface for importing spreadsheets has been improved.  The new interface provides the user with a preview of the data to be imported and interactive methods to select the desired ranges.
  • The user manual, in its Info and HTML versions, now includes graphical output examples and screenshots.
  • New command SHOW SYSTEM to easily print system information useful in bug reports.
  • Build changes:
    • Perl is no longer required to build.
    • Build now requires Python 3.4 or later.  (Building PSPP 1.4.0 also required Python, but it wasn't properly documented at the time.)
    • The Cairo and Pango libraries are now required.
    • gettext 0.20 or later is now required.
    • gtksourceview 4.x is now supported (3.x also remains supported).
  • Output improvements:
    • New drivers for output to TeX source files and to PNG files.
    • Table output styles may now be set with the new option --table-look and the new SET TLOOK command.
    • New driver option "trim" to remove empty space from PDF, PostScript, SVG, and PNG output files.
    • The PDF output driver now adds an outline to allow PDF viewers to display as a "table of contents" for the file.
    • The HTML output driver has a new option "bare".
  • New features in pspp-output:
    • New --table-look and --nth-commands options.
    • New get-table-look and convert-table-look commands.
