Confidence: probability, band, window

A forecast is rarely a single certain number. Each definition or entry can carry confidence on three axes:

• probability: how likely the event is to happen at all (100% means certain).
• band: a low/high range around the amount, as a percentage of the expected amount or as absolute low/high figures. Northwind orders carries an 80%/120% band.
• window: how many days before or after the expected date the event might land.

Confidence feeds the projection's fan chart and its probability-of-negative. See *Read the projection*.
