What's New in SPSS AnswerTree 3.1?
SPSS AnswerTree 3.1 offers many new features and productivity enhancements including:
- Enhanced scalability and performance
- more effectively solve enterprise-sized problems. Disk space requirements for processing large data files are now reduced due to the use of cache compression and improved temporary file management.
- Enhanced tree duplication - get enhanced efficiency. You now have the ability to create new trees based on existing trees in the project.
- Show split statistics
- enhance your model understanding and insight by showing/hiding split statistics conveniently within the tree. For splits using ordinal predictor variables, you can display categories as ranges or discrete values.
- Repeatable tasks are simplified
- simplify repeatable tasks (such as running weekly reports). You can now generate scripts automatically from the user interface and run them on a Solaris or Windows NT platform.
- Enhanced connectivity with other SPSS Inc. products
- extend your export options; the production mode now exports PMML-compliant files. For instance, use SmartScore to interpret AnswerTree's PMML models and use them to score new cases.
- General Usability Enhancements -
- Get added control and efficiency. The Data Properties dialog box now allows you to view data properties before creating the root node.
- More efficiently define intervals for continuous predictor variables in CHAID analyses by using the Intervals tab in the Advanced Options dialog box. Access this dialog from the new Tree Wizard
or from the Analysis menu after the tree is grown.
- More efficiently change the measurement level of predictor variables using the Measurement Level dialog box. You can also change measurement levels before you grow the tree in the Model
Definition step of the New Tree Wizard.
- The Define Variables dialog box has been eliminated. Perform the same tasks more efficiently using the new Data Properties and Measurement Level dialog boxes and the Advanced Options, Intervals
tab.
- Enhanced robustness - many underlying enhancements enable you to explore your data with unprecedented levels of convenience, control, and confidence
What's new in SPSS AnswerTree 3.0?
These features are new in SPSS AnswerTree 3.0 and are also available in SPSS AnswerTree 3.1.
- Scalability and performance
- the algorithms in AnswerTree 3.0 were rewritten for more scalability. A client-server version is now available to process data on more powerful servers and reduce network traffic to clients.
- Model evaluation graphs - AnswerTree now includes interactive evaluation graphs - gains, response, lift, profit ROI charts - to help you pinpoint the place where the model is most effective.
- Multi-page print preview, expand and collapse branches and improved zooming
- highly requested usability enhancements; these features help users understand results more quickly and better manage large trees.
- Improved production mode - from the user interface, you can automatically generate scripts for automated "production" jobs (for common tasks such as refreshing a model).
