| Calibration is the process of finding simulator input values for a historical time period which reproduce the observed simulator outputs over that period. To accomplish this a distinct calibrator framework is created alongside the simulator framework, within the same model family (see [[concepts:How it's Organized]]). There are two main motivations for calibration. The first is to look back at the history of a system through the same conceptual framework used to explore the future of that system - a prerequisite for trend analysis. The second is to get starting values - or initial conditions - of model stocks. | Calibration is the process of finding simulator input values for a historical time period which reproduce the observed simulator outputs over that period.
