We use VECM because of cointegration. When the variables are cointegrated, OLS will be consistent, w ...
您好,我有个问题不太明白,想向您请教一下
Assuming that the series f and s are cointegrated, formulate and estimate a general ECM and using appropriate information criteria and diagnostic tests, 'test down' to a more parsimonious model.
我按照要求用E-G两步法做出了ECM: df=-0.000195+0.2444ds+0.01857u(t-1)+vt
接下来应该做那些诊断检验来完善模型?
非常感谢您的帮助!
