Driver analysis

A driver analysis visualization shows you the key drivers, or predictors, for a target. The closer the driver is to the higher value on the scale, the stronger that driver is, thus, a significant predictor.

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.

Key drivers for both continuous and categorical targets are available in the driver analysis visualization in dashboards and explorations.

The following example is a driver analysis visualization that shows the predictors of the target, Total Claim Amount:

The predictors, or key drivers, have a weak or strong predictive strength that depends on where they are on the scale.

Note:

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

If you hover over a data point, then the driver analysis visualization shows what drives the total claim amount:

Driver analysis visualization that shows what drives total claim amount with information while hovering over a data point.

The driver analysis visualization shows that the combination of vehicle class, location type, coverage, marital status, and employment status are the strongest drivers of the Total Claim Amount target.

Note: Filters are not supported for driver analysis visualizations.

Sample dashboards

A driver analysis visualization is available in the Policy analysis dashboard, on the CLTV tab.
