Preparing Data for Analysis (Data Audit)

The Data Audit node provides a comprehensive first look at the data you bring into IBM® SPSS® Modeler. Often used during the initial data exploration, the data audit report shows summary statistics as well as histograms and distribution graphs for each data field, and it allows you to specify treatments for missing values, outliers, and extreme values.

This example uses the stream named telco_dataaudit.str, which references the data file named telco.sav. These files are available from the Demos directory of any IBM SPSS Modeler installation. This can be accessed from the IBM SPSS Modeler program group on the Windows Start menu. The telco_dataaudit.str file is in the streams directory.
