称为一阶误差修正模型(first-order error correction model)。 (**)式可以写成: # _( {! Y* `2 _+ U 其中:ecm表示误差修正项。由分布滞后模型知:一般情况下|μ|<1 ,由关系式μ得0<λ<1。可以据此分析ecm的修正作用: (1)若(t-1)时刻Y大于其长期均衡解α0 + α1X,ecm为正,则(-λecm)为负,...
Based on the theory of time series error correction model,this paper attempts to establish the error correction model(ECM) to support the short-term electricity price forecasting.The data of electricity price and its influencing factors are preprocessed for stationarity through the difference.The autore...
the total data of import and export trade from the 1st quarter of 2000 to the 3rd quarter of 2007 are chosen to establish the error correction model between the import-export trade and the economic growth through using the econometrics methods of ADF unit root test,Granger causality test as ...
Figure 2: Model architecture of FastCorrect. Experimental results Researchers reported the accuracy and latency of different error correction models on AISHELL-1 and on an internal dataset, as shown in Table 1. We made several observations: 1) The autoregressive (AR)...

This paper is concerned with using the bootstrap to obtain improved critical values for the error correction model (ECM) cointegration test in dynamic models. In the paper we investigate the effects of dynamic specification on the size and power of the ECM cointegration test with bootstrap critica...
