Statistics Seminar（2017-09）

Topic:Inference in Threshold GARCH Models

Speaker:Dong Li, Associate Professor, Center for Statistical Science, Tsinghua University

Time:Thursday, May 11, 14:00-15:00

Place:Room 217, Guanghua Building 2

Abstract:

This talk studies the asymptotic theory of the quasi-maximum likelihood estimation for a threshold GARCH model. Under some conditions, it is shown that the estimated threshold is n-consistent, which converges weakly to the smallest minimizer of a two-sided compound Poisson process. The remaining parameters are root-n-consistent and asymptotically normal. Simulation studies are carried out to assess the performance of the estimator. Finally, an empirical example is given to illustrate the usefulness of TGARCH models.
