Baseline extrapolation is a method of forecasting that involves using historical data to project future trends. It assumes that the past patterns will continue into the future, making it useful in situations where there is little or no reason to believe that underlying conditions will change.

Baseline extrapolation is used within our platform in two ways: in the form of the Baseline Scenario, which is typically set without any modifiers or assumptions for comparison purposes; and in the baseline forecast, the first step within our scenario forecasting process, after which modifiers and assumptions are applied.
