Two new extension commands have been posted on the SPSS Community site, and one other has an update.

STATS COXREGR performs Cox regression.  It adds some features not available in the built-in COXREG command - principally interval-based censoring using a counting process.  It requires the R Essentials.

STATS VALLBLS FROMDATA creates value labels for a set of variables based on values of other variables in the dataset.  Variables can be specified by name or via patterns in the names.  Conflicts in the labels and duplicate labels are reported.  It requires the Python Essentials.

Both extensions include a dialog box interface and traditional SPSS syntax.

STATS ADJUST WIDTHS, which synchronizes string variable sizes across datasets to facilitate merging, has a bugfix for the VARIABLES=ALL case.

The Python Essentials can be installed via the SPSS Community website (www.ibm.com/developerworks/spssdevcentral), or, for V21, via the media for that version.  For V22, the Python Essentials are integrated into the main Statistics install.

The R Essentials can be installed via the website.

For Statistics 22, new extensions and updates can be installed from the Utilities > Extension Bundles > Download and Install Extension Bundles menu.  For older versions of Statistics, these items need to be downloaded from the website and installed.

Reminder: If you are on Windows 7 or similar, extensions usually need to be installed using Run As Administrator.

We hope that you find these useful.
