Witryna5 wrz 2024 · Only I ( d) series with d ≥ 1 can enter the cointegration relationship. Thus I (0) series will never belong in a cointegration relationship. At least two of the series must share the highest order of integration to cointegrate. E.g. three {I (2), I (2), I (1)} processes can cointegrate but {I (2), I (1), I (1)} cannot.

You can find the order of integration by differencing the given variable at different lags and see when it become stationary. So if the variable is not stationary at first lag and become stationary at first difference, the variable is integrated of order 1, i.e. I (1). Witryna21 cze 2016 · Unit-root tests in Stata. Determining the stationarity of a time series is a key step before embarking on any analysis. The statistical properties of most estimators in time series rely on the data being (weakly) stationary. Loosely speaking, a weakly stationary process is characterized by a time-invariant mean, variance, and …

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. counterdemand definition
