平稳时间序列预测法

　　时间序列 取自某一个随机过程，如果此随机过程的随机特征不随时间变化，则我们称过程是平稳的；假如该随机过程的随机特征随时间变化，则称过程是非平稳的。

-Stationary time series prediction

Time series from a single random process, if the random process of random feature does not change over time, then we say that the process is smooth　if the random characteristics of the random process over time, claimed that the process is non stationary.
