WebCointegration theory may establish a long-term stable relation between several time series with the same order of integration, and their linear combination may reduce the order of integration. Using cointegration theory, the corresponding relation between variables can provide an accurate judgment. WebAn important cointegration theorem is the Granger representation theorem (GRT). This theorem states that if a system of variables is cointegrated in a given sample, the growth rates in at least one of the variables involved in the cointegrated system must be forecastable by the cointegrating residual, in this case pt − dt.
