用于研究时间序列的方法有AR(自回归)、MA(滑动平均)、ARMA(自回归滑动平均)这三种模型。而对于一个平稳时间序列预测问题,首先要考虑的是寻求与它拟合最好的预测模型。而模型的识别与阶数的确定则是选择模型的关键。 1.用 迭代生成1000个点(前2个点自定义)。 2.在这1000个点中取800点进行时间序列分析建立合适的模型。 3.利用剩余的200个点进行模型预测,并看其是否匹配,最后校正。 -Methods for studying time series are AR (autoregressive), MA (moving average), ARMA (autoregressive moving average). For a stationary time series prediction problem, the first thing to consider is to find the best prediction model with it. And the identification of the model and the order of the selection is the key to the selection model. 1. Use iteration to generate 1000 points (the first two points to customize). 2. Take the 800 points in the 1000 points for time series analysis to establish the appropriate model. 3. Use the remaining 200 points to model the forecast and see if it matches and finalize it.

ARIMA模型全称为自回归积分滑动平均模型(Autoregressive Integrated Moving Average Model,简记ARIMA),是由博克思(Box)和詹金斯(Jenkins)于70年代初提出一著名时间序列预测方法[1] ,所以又称为box-jenkins模型、博克思-詹金斯法。其中ARIMA(p,d,q)称为差分自回归移动平均模型,AR是自回归, p为自回归项; MA为移动平均,q为移动平均项数,d为时间序列成为平稳时所做的差分次数。所谓ARIMA模型,是指将非平稳时间序列转化为平稳时间序列,然后将因变量仅对它的滞后值以及随机误差项的现值和滞后值进行回归所建立的模型。ARIMA模型根据原序列是否平稳以及回归中所含部分的不同,包括移动平均过程(MA)、自回归过程(AR)、自回归移动平均过程(ARMA)以及ARIMA过程。(To address time consuming and parameter sensitivity in the emerging decomposition- ensemble models, this paper develops a non-iterative learning paradigm without iterative training process.)
