Based on the assumption that the wavelet is non-causal and mixed phase,both the moving average(MA) and autoregressive moving average(ARMA) models were introduced to fit the seismic record.
在地震子波非因果、混合相位的假设下,分别应用滑动平均(MA)和自回归滑动平均(ARMA)模型对地震记录建模,并采用基于高阶累积量的线性方程法对子波提取和模型适应性进行了研究。
This paper,based on Auto Regressive Moving Average(ARMA),presents a traffic predictor that uses group model,using time series to build the mathematic models.
基于自回归滑动平均模型(ARMA),利用时间序列建模,提出了利用组合模型对网络流量进行预测的方法。
