摘要
本文讨论了地震异常和干扰因子失稳对前兆序列建模的影响,提出了采用门限回归和反馈修正观测值减弱这种影响的门限反馈(MF)模型。实例计算效果良好。
It is discussed that the seismic anomaly and the interference factor destabilization have an influence on setting up the precursor sequence model. The threshold feedback (MF) model with threshold regression and feedback modified observation is given. It may reduce the influence. The example proved that MF model is a practicable one for predicting precursor sequence normal dynamic background value.
