Spiral

A spiral visualization shows you the key drivers, or predictors, for a given target. The closer the driver is to the center, the stronger that driver is.

IBM® Cognos Analytics uses sophisticated algorithms to deliver highly interpretable insights that are based on complex modeling. You don't have to know which statistical tests to run on your data. Cognos Analytics picks the right tests for the data.

For more information, see Statistical tests.

You can exclude drivers from the analysis. Right-click on a driver and click the Edit drivers icon Edit drivers icon. Select the drivers that you want to include in the analysis.

To edit or add key drivers, click the More icon on the target field.

To improve performance, due to number of rows in the data source, the analysis is based on a representative sample of the entire data.

The following image shows an example of a spiral visualization.
