Note—An Application of Closed-Form Error Analysis to Fiscal Impact Models

For a variety of reasons, predictive power is not always a useful criterion of model validity. One alternative is a closed-form analysis of error propogation, but often the exact functional form is too unwieldy to use. A similar analysis is performed here, using a Taylor series approximation to the impact-multiplier submodel of a fiscal impact model, developed for coal and oil shale assessment.
