Note—An Application of Closed-Form Error Analysis to Fiscal Impact Models
针对预测能力不足以衡量模型有效性的情况，采用泰勒级数近似对煤炭和油页岩评估中的财政影响模型进行闭式误差分析。
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.
