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 cointegration relationship (or combination) β′yt β ′ y t would then be given by, β′yt = β1y1,t +β2y2,t ∼ I (0) β ′ y t = β 1 y 1, t + β 2 y 2, t ∼ I ( 0) Hence, the nonstationary variables in the yt y t vector are cointegrated if there is a linear combination of these variables that is stable (stationary). WebThe Latin word data is the plural of datum, " (thing) given", neuter past participle of dare, "to give". [6] The first English use of the word "data" is from the 1640s. The word "data" was first used to mean "transmissible and storable computer information" in 1946. The expression "data processing" was first used in 1954.
