中文说明：资源描述时间序列是基于已观测的振动信号，采用arma模型来对观测到的信号进行拟合训练，得到较好的模型，然后进行预测，ARMA模型适合短期预测，并且效果较好。现在已经广泛应用在机械振动的预测和处理。该程序可以实现对未来振动信号的预测。
English Description：
Application backgroundTime series is based on the observed vibration signal, using the ARMA model to fit the observed signal to train, get better model, and then forecast, ARMA model is suitable for short-term forecasting, and the effect is better. Now widely used in the prediction and treatment of mechanical vibration. The program can be achieved for the prediction of future vibration signals.
