Outline of Final Research Achievements |
When we analyze data using time series models, there are many steps such as model selection, estimation of parameters, and diagnostic checking. Generally, since these steps are separately implemented, time series data analysis is complicated. Also, interpretation is difficult when the results of these steps are different. Therefore, we propose empirical likelihood methods that can compute these simultaneously, and elucidated that it has excellent properties especially in diagnostic checking. Simulation studies also showed that the proposed method performed equally or better than the usual method in many cases.
