• For this example – AIC selects p=3 – BIC selects p=2 • Notice that the AIC value for p=3 in this table (AIC=7.572) is different from that obtained when 16.1 Vector Autoregressions. A Vector autoregressive (VAR) model is useful when one is interested in predicting multiple time series variables using a single model. At its core, the VAR model is an extension of the univariate autoregressive model we have dealt with in Chapters 14 and 15.

build a structural model for Germany with a transparent and theoretically coherent foundation. The modelling strategy consists of a set of long-run structural relationships suggested by economic theory and an otherwise unrestricted VAR model. It turns out that we can rebuild the structure of the model in Aug 02, 2016 · Cointegration – Johansen Test with Stata (Time Series) In the previous discussion we had shown that how we do the cointegration test what we called it as Engle and Granger test . This test has the advantage that it is intuitive, easy to perform and once we master it we will also realize it limitation and why there are other tests.

Details. Currently, the methods for the generic function grangertest only perform tests for Granger causality in bivariate series. The test is simply a Wald test comparing the unrestricted model—in which y is explained by the lags (up to order order) of y and x—and the restricted model—in which y is only explained by the lags of y. The plot gives the response of series 2 for the periods 0 to 20 to a shock in series 1 in period 0. The function also automatically calculates so-called bootstrap confidence bands. (Bootstrapping is a common procedure in impulse response analysis. But you should keep in mind that it has its drawbacks when you work with structural VAR models ...
