Preferred term

cointegration  

Definition

  • When a linear combination of nonstationary variables is stationary, the variables are said to be cointegrated, and the vector that defines the stationary linear combination is called a cointegration vector. A time series is stationary if its distribution does not vary over time. [Source: The SAGE Encyclopedia of Social Science Research Methods; Cointegration]
