OLAP Miner User's Guide


Viewing deviations in the main window

After you run a deviation detection definition, a results file is created. If you select this results file, a list of results is displayed in the right pane of the OLAP Miner main window. These results are not shown in context of other surrounding values. The deviations are listed by highest magnitude to lowest magnitude. Deviations with the same magnitude are sorted according to the difference in their absolute residual values. The deviations with the same magnitude that have a greater difference in residual values are sorted first. The most important deviations, based on magnitude, are displayed at the top of the list.

The OLAP Miner main window with deviations

When you select a results file from the left pane of the main window, a list of deviations is displayed in the right pane. Across the top of the right pane, the dimensions that you selected for your deviation detection definition are displayed. Also, as shown in Figure 1, two more column headings are added: Expected and Magnitude.

The Expected column shows whether the expected value of a cell is higher or lower than the actual value of that cell.

Magnitude shows that there is a greater or lesser difference between the expected value and actual value of the cell. For more information about how OLAP Miner determines expected values and magnitude, see The OLAP Miner algorithm.
