【摘要】 本文从系统结构的时变性出发,将常定回归系数的数学模型拓展为时变回归系数的动态回归模型。通过实践证明,它更具有实用性,这为今后的定量分析提供了一种较有实际意义的数学模型。更多还原

【Abstract】 In the paper, according to time—variability of Systematic structure, the author developed the model with constant regression parameter into the dynamic linear regression model with time—variable regression parameter. Practically proof, it has great real—applicability, which may provides a rather practical mathematic model for the quantitive analysis in future.更多还原
