摘要 本文对一般时变自回归模型(TVAR)的时变系数提出一种估计方法,即建立一个关于时变系数的向量自回归时间序列模型,利用最小二乘方法计算其系数矩阵,在此基础上预测时变系数,从而得到时变自回归序列的点预测,另外给出了点预测和区间预测的方法. By establishing the vector auto-regression time series model,the authors use least square algorithm to estimate the model's parameter matrix and predict the time-varying parameters of a time-varying auto-regression (AR) model.Based on above conclusion,finally we present a method for point prediction and interval prediction.
