Tactical and Strategic BIAS

The BIAS summary statistic (sum-stat) is calculated by the forecast engine.

The BIAS sum-stat is calculated when:

  • The Forecast From Date is set to a new weekly or monthly period.
  • The net history within the last period of a Planning Entity (PE) is updated.

This sum-stat is calculated using Sales Units and is displayed on the Details and Accuracy tabs of the Information panel.

The sum-stats are displayed as:

  • Strategic BIAS: SBIAS on the Details tab.
  • Tactical BIAS: TBIAS on the Details tab.
  • Bias error on the Accuracy tab.

You can use the Lucene query to search for a range of sum-stats in the Selection panel. For example, if you specify the "sum_stats.TBIAS:[-20 TO 30]" query in a search, PEs or APEs with TBIAS sum-stats values within the range of 20 and 30 are displayed in the Selection panel.

Note: 
  • The BIAS sum-stat is calculated for PEs and forecasting APEs.
  • If this sum-stat is calculated and updated for a base PE, the sum-stat is automatically recalculated and updated for all associated APEs.
  • This sum-stat is displayed on the Details tab only after changes to the net history of the PE or APE is saved.
