Canonical correlation and reduction of multiple time series Academic Article uri icon


  • It is shown that a degenerate rank d-variate stationary time series can be reduced to a full rank time series of lower dimension via an orthogonal transformation T provided that , the canonical correlation between past and future of the time series is strictly less than one. Procedures for estimation of rank of the multiple time series, T and testing =1 are outlined, the latter is related to testing the unit root hypothesis in ARMA models. 1994 The Institute of Statistical Mathematics.
