This is because change point problems can be encountered in many fields such as economics, finance, medicine and so on. In this project, we firstly provide a comprehensive review of several popular tests in detecting mean and variance shift. To investigate the performance of those tests, Type I error and power are examined followed by two empirical investigations. Our results show that for mean shift detection, both K&L test and ARMA residual test work well for normal distributed process; for ARMA process, the ARMA residual test is the best; for variance shift detection, change in mean has huge influence on Type I error estimation and I&T test is more powerful than K&L test for GARCH process. 2014-12-01 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1417195911 http://rave.ohiolink.edu/etdc/view?acc_num=miami1417195911 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
