SPSS Statistics releases with new features typically occur at intervals of
a year or more. Extension commands, however, are added and updated
much more frequently. Following is a possibly incomplete list of new
and updated commands for 2023.
Some may be installed automatically with
the SPSS installation, but any of them can be installed or updated via
Extensions > Extension Hub in Statistics. In particular, the new
STATS EXTENSION REPORT command generates a report on what extensions
you have installed. It can't identify commands where an update is
available, but the Extension Hub display can show that information.
SPSSINC RAKE
a fix for the case where sometimes missing data on a control
variable would cause the display of the weights table to fail.
This did not affect the actual weight calculation or the plots, which were
correct.
STATS UPDATE
a new extension that provides a dialog box interface for the
built-in UPDATE command, which lacks its own dialog box.
SPSSINC GETURI DATA
An update to support https URLs on the Mac (pending)
STATS IMBALANCED
a new extension that does SMOTE sampling on unbalanced datasets to improve
performance with rare outcome categories
SPSSINC TRANS
a major update that greatly increases the sort of code that can be used in the
formula and gives better error messages
SPSSINC MODIFY TABLES
a major update that allows tables to be shown as a heatmap, where
color attributes reflect the selected cell values. Also, a
color picker can be used in the dialog box to set colors visually rather
than requiring RGB values.
STATS POP DESCRIPTIVES
a replacement for an older custom dialog box as a full extension command thus
eliminating the messy syntax that was displayed in the Viewer
STATS CONVERT PYTHON
a minor update to handle a quirk in the Python code converter.
STATS MAKE CASES
an upgrade of a custom dialog box to a full extension. This extension
generates a dataset of random variables that follow any of twenty distributions and can be
correlated. These are all distributions that can be generated by the regular SPSS random
number generators except for the triangular distribution, which is provided here, but it
handles all the case generation eliminating the need to write an input program,
and it has a dialog box interface as well as regular syntax.
STATS RELIMP
a major update to support imputed datasets plus some other
minor improvements. This extension is useful in variable selection in
regression and provides a number of importance measures,
including the Shapley value.
STATS PSM and FUZZY
A major upgrade to the matching algorithm that will tend to give better matches.
STATS EXTENSION REPORT
a new procedure that produces a report on all the extension commands installed
STATS PREPROCESS
a new procedure that provides a variety of transformations to modify
variable distributions. Among other things, it includes Yeo-Johnson
and Box-Cox transformations to normality.
STATS TEXTANALYSIS
Support added for rudimentary analysis of German text.
SPSSINC PROCESS FILES
a major update that simplifies the use of this procedure and now comes with
a tutorial document. It is not quite 100% compatible with the previous version,
but that is now available as SPSSINC PROCESS FILESORIG.
