摘要
回归预测技术应用广泛,方法理论较成熟;时间序列分析则是经济模型构造的进一步研究方向。实际应用中,两种方法都有局限性。作为这两者的组合,本文详细阐述了回归-时序(R-T)组合预测模型的建立,并用之对耕整机的发展作了科学的预测。
The technigue of regression forecast is widely used and its theoryis fairly well developed. Analysis of time series method is the further researchdirection in establishment of an economic model; however both methods havetheir limited practical applications, and as a combination of the two methods,(R-T) combination forecasting model is described in detail in its establishment.The result of forecasting by using this model in the development of paddy fieldtillage machines is sotifactory.
