IBM SPSS Modeler supports Python scripting using Jython, a Java[tm] implementation of the Python language. Modeler versions 16 and 17 use Jython 2.5.1 which includes a number of useful and popular modules. However, many other modules are available and customers often want to use their own so a frequent question is how to include them. There …

Most SPSS Modeler scripts include code that locates an existing node e.g.: stream = modeler.script.stream() typenode = stream.findByType(“type”, None) However, some scripts need to search for all nodes – maybe by node type but also matching some other criteria. The Modeler scripting API documentation (PDF) mentions a findAll() function: d.findAll(filter, recursive): Collection filter (NodeFilter) : the node filter recursive …

Contemporary analytical platforms like SPSS and SAS represent the some of the earliest and yet longest-lived examples of proprietary software in the industry. When we think of the tectonic shifts the technology landscape has witnessed in last four decades, through the mainframe era, the rise of the PC, browser wars, the dotcom bubble, the smartphone …
How alternative interfaces can help you get more out of R Read More »
Many of the analysts we speak to are being pushed over to R, primarily because it’s open source and therefore a free alternative to commercial data analytics packages for which the costs can sometimes run into tens of thousands of pounds (or more). However, even experienced analysts often find that getting to grips with R …
This post describes how to use Python scripts to create and modify Modeler supernodes, and control the execution of the nodes within the supernode. If you’re after a basic overview of Python scripting in Modeler then this post may be of interest, and I’ve also written about how to write standalone Python scripts in Modeler here. As …
In my last post I gave a brief overview of the new Python-based scripting available in Modeler 16. In this post, I will cover Modeler 16 scripting in a little more detail. This assumes some familiarity with Python such as the Python module mechanism and exception handling. There are three types of script in Modeler: …
Modeler scripts are used to automate the creation of streams, construction and configuration of nodes, stream execution and managing the execution results such as saving models to file or a content repository. A major new feature in Modeler 16 is the introduction of Python as the default scripting language. Python replaces the original bespoke language Modeler …
