摘要:
定义了连续情形的预测精度公式，在此基础上给出了１套衡量定量预测方法有效性指标的一般定义，并讨论了几类有效度之间的关系，同时给出了估计拟合有效度、预测有效度的具体方法。从而给预测工作者选择有效的预测方法提供了可靠的理论基础，减少预测工作的盲目性和预测费用。
Abstract:
The prediction accuracy formula for continuous situations is defined, and on this basis, a general definition of the effective indicator of the effective indicator of the quantitative prediction method is given, and the relationship between several types of effectiveness is discussed. At the same time, it gives specific methods for estimating the effectiveness of the fitting and the effectiveness of the prediction. Therefore, it provides a reliable theoretical basis for predictors to choose effective prediction methods, and reduce the blindness and prediction costs of prediction work.
