Browsing model nuggets

The model nugget browsers enable you to examine and use the results of your models. From the browser, you can save, print, or export the generated model, examine the model summary, and view or edit annotations for the model. For some types of model nugget, you can also generate new nodes, such as Filter nodes or Rule Set nodes. For some models, you can also view model parameters, such as rules or cluster centers. For some types of models (tree-based models and cluster models), you can view a graphical representation of the structure of the model. Controls for using the model nugget browsers are described below.

Menus

File menu. All model nuggets have a File menu, containing some subset of the following options:

  • Save Node. Saves the model nugget to a node (.nod) file.
  • Store Node. Stores the model nugget in an IBM® SPSS® Collaboration and Deployment Services repository.
  • Header and Footer. Allows you to edit the page header and footer for printing from the nugget.
  • Page Setup. Allows you to change the page setup for printing from the nugget.
  • Print Preview. Displays a preview of how the nugget will look when printed. Select the information you want to preview from the submenu.
  • Print. Prints the contents of the nugget. Select the information you want to print from the submenu.
  • Print View. Prints the current view or all views.
  • Export Text. Exports the contents of the nugget to a text file. Select the information you want to export from the submenu.
  • Export HTML. Exports the contents of the nugget to an HTML file. Select the information you want to export from the submenu.
  • Export PMML. Exports the model as predictive model markup language (PMML), which can be used with other PMML-compatible software. See the topic Importing and exporting models as PMML for more information.
  • Export SQL. Exports the model as structured query language (SQL), which can be edited and used with other databases.
    Note: SQL Export is available only from the following models: C5, C&RT, CHAID, QUEST, Linear Regression, Logistic Regression, Neural Net, PCA/Factor, and Decision List models.
  • Publish for Server Scoring Adapter. Publishes the model to a database that has a scoring adapter installed, enabling model scoring to be performed within the database. See the topic Publishing models for a scoring adapter for more information.

Generate menu. Most model nuggets also have a Generate menu, enabling you to generate new nodes based on the model nugget. The options available from this menu will depend on the type of model you are browsing. See the specific model nugget type for details about what you can generate from a particular model.

View menu. On the Model tab of a nugget, this menu enables you to display or hide the various visualization toolbars that are available in the current mode. To make the full set of toolbars available, select Edit Mode (the paintbrush icon) from the General toolbar.

Preview button. Some model nuggets have a Preview button, which enables you to see a sample of the model data, including the extra fields created by the modeling process. The default number of rows displayed is 10; however, you can change this in the stream properties.

Add to Current Project button. Saves the model nugget and adds it to the current project. On the Classes tab, the nugget will be added to the Generated Models folder. On the CRISP-DM tab, it will be added to the default project phase.
