回归预测分析技术应用广泛,方法理论较成熟;时间序列分析是经济模型构造的进一步研究方向。但在实际应用中,两种方法都有其局限性。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: The regression prediction analysis technique is widely used and the method theory is relatively mature. Time series analysis is the further research direction of economic model construction. However, in practical application, both methods have their limitations. As a combination of the two, this paper elaborates on the regression-timing (R-T) combined forecasting model:
