Generalized Predictive Tests and Structural Change Analysis in Econometrics
提出一种广义预测检验方法,用于非线性动态联立方程模型的结构稳定性分析,基于易计算的预测残差,允许小预测子样本和数据驱动的模型选择,并能逐方程或全局分析结构变化的时间和形式。
A generalized predictive testing procedure for structural stability in nonlinear dynamic simultaneous equations models is presented. It has several attractive features: (1) the tests are based on easy-to-compute predicted residuals; (2) the prediction subsample can be arbitrarily small; (3) only consistency is required and allowance is made for data-based model selection; (4) it is possible to analyze the timing and form of structural change equation by equation or globally, allowing an exploratory analysis of structural change conveniently summarized in a predictive analysis table; and (5) general forms of temporal dependence between model disturbances are allowed.
