| Suppose you have a model with a coefficient in it which is NOT measured, for example an efficiency coefficient for a widget, and you need to estimate that coefficient. In historic time you have a good estimate of the number of widgets and the amount of energy used by the widgets (observedEnergyUse). You need to find an value for your coefficient that when multiplied by the number of widgets results in an energy use amount that tracks as close as possible to the observedEnergyUse. A feed back view can be used to run the model check the difference in energy use, modify the coefficient appropriately, run the model again, and continue this loop until some acceptable level of convergence is achieved. | Suppose you have a model with a coefficient in it which is NOT measured, for example an efficiency coefficient for a widget, and you need to estimate that coefficient.
