PSPP 0.8.3 has been released

Item posted by Ben Pfaff <blp> on Fri 25 Apr 2014 05:18:30 AM UTC.

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 0.8.2 to 0.8.3:

  • Independent T-Tests displayed the standard error of the difference and the confidence interval for the unequal variances case, where the equal variances case should have been.  This has been fixed.
  • REGRESSION now recognises /STATISTICS=CI(x) which causes confidence intervals for the coefficients to be printed.
  • When DESCRIPTIVES calculates Z scores, it now omits cases filtered by the current FILTER settings.
  • PSPPIRE graphical user interface improvements:
    • Dialog boxes with source variable lists can now choose the sort order; right click and select from the popup menu.
    • File|Open now allows an encoding to be selected for opening system files.
    • File|Display Data File Information|External File... now allows an encoding to be selected.
    • A problem with the Means dialog has been resolved (bug #41433).
    • Several problems related to the input of spreadsheets have been fixed (bug #41657, #41620)
  • System file related improvements:
    • With ENCODING="DETECT", SYSFILE INFO can now help the user to pick an encoding for reading a system file that does not identify its own encoding
    • SYSFILE INFO now accepts an ENCODING subcommand to specify the character encoding of string data in the system file.
    • Variable labels over 255 bytes long are now accepted without truncation (bug #41863).
    • System files that contain duplicate variable names may now be read successfully (bug #41475).
