自回归模型 Autoregressive model

（重定向自Autoregressive）

自回归模型（英语：Autoregressive model，简称AR模型），是统计上一种处理时间串行的方法，用同一变量例如x的之前各期，亦即x_{1}至x_{t-1}来预测本期x_{t}的表现，并假设它们为一线性关系。因为这是从回归分析中的线性回归发展而来，只是不用x预测y，而是用x预测x（自己）；所以叫做自回归。

自回归模型被广泛运用在经济学、信息学、自然现象的预测上。

Autoregressive model 自回归模型

（重定向自Autoregressive）
AR(0); AR(1) with AR parameter 0.3; AR(1) with AR parameter 0.9; AR(2) with AR parameters 0.3 and 0.3; and AR(2) with AR parameters 0.9 and −0.8

In statistics and signal processing, an autoregressive (AR) model is a representation of a type of random process; as such, it describes certain time-varying processes in nature, economics, etc. The autoregressive model specifies that the output variable depends linearly on its own previous values and on a stochastic term (a stochastic—an imperfectly predictable—term); thus the model is in the form of a stochastic difference equation. It is a special case of the more general ARMA model of time series, which has a more complicated stochastic structure; it is also a special case of the vector autoregressive model (VAR), which consists of a system of more than one stochastic difference equation.
