WebJul 22, 2016 · Two series with I (1) trends can be co-integrated only if there is a genuine relationship between the two. Thus the standard current methodology for time series regressions is to check all-time series involved for integration. Webthe Johansen-Fisher developed by Maddala and Wu (2001) (iv) the Westerlund (2007) method. The first assumes homogeneity on cross-sectional units and is based on the Engle-Granger two-step procedure. Cointegration is tested with the ADF test. The second encompasses seven tests, which are residual based.

Cointegration is a statistical property of a collection (X1, X2, ..., Xk) of time series variables. First, all of the series must be integrated of order d (see Order of integration). Next, if a linear combination of this collection is integrated of order less than d, then the collection is said to be co-integrated. Formally, if … See more If two or more series are individually integrated (in the time series sense) but some linear combination of them has a lower order of integration, then the series are said to be cointegrated.

WebThe idea of cointegration is that there is a common stochastic trend, an I(1) process Z, underlying two (or more) processes X and Y. E.g. Xt = 0 + 1Zt + t Yt = 0 + 1Zt + t t and t are stationary, I(0), with mean 0. They may be serially correlated. Though Xt and Yt are both I(1), there exists a linear combination of them which is stationary: 1Xt ...
