我们描述了有利于多步预测的条件,或者多步预测的动态估计。一个分析示例显示了动态估计(DE)如何在预测结果改变时适应不正确指定的模型,从而提高对某些错误规格的预测性能。然而,在正确指定的模型中,减少有限样本偏差并不能证明DR的合理性。在综合过程的蒙特卡罗预测研究中,在忽略负移动平均误差的情况下估计单位根可能有利于DR,尽管存在其他解决方案。第二个蒙特卡罗研究得到了估计量偏差,并使用渐近逼近解释了这些偏差。
We delineate conditions which favour multi-step, or dynamic estimation for multi-step forecasting. An analytical example shows how dynamic estimation (DE) may accomodateincorrectly-specified models as the forecast lead alters, improving forecast performance for some mis-specifications. However, in correctly-specified models, reducing finite-sample biases does not justify DR. In a Monte Carlo forecasting study for integrated processes, estimating a unit root in the presence of a neglected negative moving-average error may favour DR, though other solutions exist to that scenario. A second Monte Carlo study obtains the estimator biases and explains these using asymptotic approximations.
