| Abstract: | In this paper, we depict the basis theory of threshold autoregressive model and establish the self-exciting threshold autoregressive model SETAR（2,4,3） for the time series of the maximal earthquake magnitude occurring in Northeast China. The results show that the model prediction accuracy is higher. It is significant for the investigation of the earthquake activity trend prediction in Northeast China in the future. |
