pspp-0.8.3 released [stable]

[Ben Pfaff]

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.

Here are the compressed sources and a GPG detached signature[*]:
  ftp://ftp.gnu.org/gnu/pspp/pspp-0.8.3.tar.gz
  ftp://ftp.gnu.org/gnu/pspp/pspp-0.8.3.tar.gz.sig

Use a mirror for higher download bandwidth:
  http://www.gnu.org/order/ftp.html

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify pspp-0.8.3.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys C6648E90

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.11.6
  Gnulib v0.0-7913-g5191133

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).
