Overview of Top Movers calculations
Top Movers are calculated by gathering a statistically significant number of values for the monitored event or dimension over time and then calculating the standard deviation for the sampled values.
Top Movers can be calculated on a daily or an hourly basis. Tracking hourly Top Movers requires more storage capacity.
Note: Tracking of hourly Top Movers is a feature of Unica Discover.
The calculated value of the standard deviation for today is based on the values that are calculated from the configured set of prior days.
- Top Movers may be calculated based on a consecutive days or week-over-week method. The method in use is configurable.
The number of days over which the Top Mover is calculated is called the rolling window.
