A confidence interval indicates the range within which the actual price falls with a defined probability. Instead of a single value, the model delivers a corridor — for example: "The price falls between 3,200 and 4,100 euros with 90 percent probability."

The advantage over a point estimate: uncertainty becomes visible and manageable. A company can use the confidence interval for risk management, for example by issuing a guarantee for a value at the edge of the interval. This makes the financial risk calculable, and a statistical prediction becomes a binding business instrument.
