AR、MA及ARMA模型 - 知乎 - 知乎专栏
ma模型和ar大同小异，它并非是历史时序值的线性组合而是历史白噪声的线性组合。 与AR最大的不同之处在于，AR模型中历史白噪声的影响是间接影响当前预测值的（通过影响历史时序值）。
Chapter 2 Modelling Time Series | Time Series for Beginners
Two of the most common models in time series are the Autoregressive (AR) models and the Moving Average (MA) models. Autoregressive Model: AR(p) The autoregressive model uses …
Time Series Models | Towards Data Science
2020年9月22日 · AR, MA, ARMA, and ARIMA models are used to forecast the observation at (t+1) based on the historical data of previous time spots recorded for the same observation. …
Algorithm Breakdown: AR, MA and ARIMA models - Ritchie Vink
2018年9月26日 · ARIMA models are actually a combination of two, (or three if you count differencing as a model) processes that are able to generate series data. Those two models …
