Developer Central News

[Peck, Jon]

Here are some new items and recent updates for SPSS Developer Central (www.spss.com/devcentral).

 

Articles (on the site front page):

Programmability in SPSS Statistics 17:  The PowerPoint file from my SPSS Directions conference presentation in November on programmability.  It includes a short review of programmability and four examples:

-        using Python to automate tasks,

-        the new SPSSINC MODIFY TABLES extension command for advanced formatting of pivot tables,

-        the SPSSINC QUANTREG command integrating the R Quantreg package, and

-        the Statistical Explorer - a simple VB.NET application presenting results from SPSS without the SPSS user interface.

 

Writing SPSS Extension Commands: an update and expansion on this topic of the SPSS 16 article version.

 

New modules:

Mosaic and Association plots:  An R-based dialog box that does mosaic and association plots within SPSS Statistics using the R vcd graphics package.  Contributed by Dr Hans A. Grüner of the Freie Universität Berlin.  The user interface is available in English and German (according to your current SPSS user interface language setting).  It requires R, the R plug-in,  and SPSS Statistics 17.

 

SPSSINC BREUSCH PAGAN: An extension command and dialog box interface for carrying out the Breusch-Pagan test for linear model residual heteroscedasticity using the R car package.  It also requires R and SPSS Statistics 17 as well as the Python plug-in.

 

Module updates:

SPSSINC COMPARE DATASETS: This dataset comparison module now can produce a text file containing a detailed listing of every data difference between two datasets.  The previous version could produce this information in the form of binary difference variables in the dataset.  The text file is (sort of) human readable.

 

spssaux2.py:  Two new Python functions to provide easier access to information about multiple response sets.

 

spssaux3.py:   New function, GetComputations, that passes a set of case values to a new SPSS dataset, runs specified computes, and returns the results as a list.  Provides convenient access to SPSS transformation functions not readily available in the Python standard library such as t or F significance levels.

 

Other:

Python Module Documentation: The Python module documentation download has been updated.  (This does not include the spss and SpssClient module documentation that is installed with the plug-ins.)

 

R Boxplot: Example dialog box creating an R boxplot from an SPSS dialog.  This includes both the dialog box, which has a few features not built into the SPSS boxplots, and a short article explaining how to create things like this.  The dialog creates an R program directly and does not use Python or the extension command mechanism.

 

We hope that you will find these items useful.
