Null hypotheses specifying constraints on a or b are tested against the alternative hr of cointegration rank less than or equal to r, without the constraints. With the exception of federal funds, fred returns quarterly, seasonally. Test the null hypothesis that there are no cointegrating relationships among the response series composing a multivariate model. Cointegrated variables, identified by cointegration tests, can be combined to form new, stationary variables. Cointegration is an analytic technique for testing for common trends in multivariate time series and modeling longrun and shortrun dynamics. This example uses a cointegrated vector autoregression var model, also known as a. The tests also produce maximum likelihood estimates of the parameters in the vecq model, subject to the constraints. A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext.
