报告摘要：In this talk, we will introduce a semiparametric method to identify fractional cointegrated components of multivariate integrated processes, consisting of an eigenanalysis for a certain non-negative definite matrix. This method is model free and allows the order for different component of the vector series to be different and fractional-valued. Asymptotic properties of the proposed methods are investigated both when the dimension of the observable time series is fixed as sample size increases, and when it diverges slowly. Illustration with both simulated and real data sets is also reported.
