Forecasting a Nonstationary Time Series Using a Mixture of Stationary and Nonstationary Factors as Predictors
以平稳与非平稳混合因子预测非平稳时间序列
We develop a method for constructing prediction intervals for a nonstationary variable, such as GDP. The method uses a Factor Augmented Regression (FAR) model. The predictors in the model include a small number of factors generated to extract most of the information in a set of panel data on a large number of macroeconomic variables that are considered to be potential predictors. The novelty of this article is that it provides a method and justification for a mixture of…
