filter with some additional interpretation placed on it.
The moving average model is essentially a finite impulse response filter
with some additional interpretation placed on it.
为什么呢?
谢谢!!! |

ARMA is MA, then the order of the representation is finite; if it's AR or
ARMA, then the order is infinite.

google “FIR” and “IIR”,再和MA, AR比较一下.简单的说,FIR的输出只和输入有
关,IIR的输出(In general)和输入以及过去的输出都有关 |
