| Research Abstract |
In order to extend the applicability of the causal measures between economic time series the author developed, the research of 2001-2 made possible the statistical inference for causal measures on non-stationary long-range dependent cointegrated tome-series by developing feasible computational algorithm of estimating and testing for that purpose based on the whittle likelihood function. In particular, the research gave a limiting theorem of fractional Brownian motion under a set of weak conditions and on the basis of that theorem derived the limiting theory of the maximum Whittle likelihood estimator and the Whittle likelihood-ratio statistic. Those results enable extension of the conventional unit-root cointegration econometric analysis so far known. In the research a unified computation algorithm was developed for the statistical inference and the performance of the system was examined for Japan and U.S. macro economic data. The algorithm is basically a modified Hannan-Rissanen three-step method, using the Whittle likelihood function in the third step and is shown improvement over their method.
