OLAP Miner User's Guide
After you run a deviation detection definition, you are likely to see many
deviations. To understand deviations more clearly, follow this
process:
- View the deviations, starting with the most significant deviation in
descending order of magnitude.
- In the Deviation Viewer, look closely at the other deviations that are
highlighted in red. The other deviations that have higher magnitude
values might be the reason for the given deviation. (By moving the
cursor over a deviation, you can see the magnitude value and whether the
expected value is higher or lower than the actual value.)
- Continue to look through the list of deviations in the main window and
view each deviation in context by opening the Deviation Viewer. As you
read through the list of deviations, the magnitude, or importance, of the
deviations decreases. Therefore, the significance of the deviation in
the Deviation Viewer is reduced.
