讨论了3种模型(灰色模型、指数函数模型和自回归模型)对具有指数函数特征的时间序列的建模过程,比较与分析了其特点。通过3个数例对3种模型的长期预测结果进行计算与分析,结果表明:3种模型都可以用于具有指数函数特征的序列建模,并可以相互验证。 更多还原

【Abstract】 Aiming at the characteristics of exponential function,this paper had discussed,compared and analyzed the modeling process and characteristic of three models: grey model,exponential function model and autoregressive model.The computed results of three numerical examples showed that three models could be used for long-term forecast for those time series which had exponential function characteristics.They can also verify mutual. 更多还原
