ARIMA modeling actually includes three stages, namely, model identification stage, parameter estimation and verification stage, and prediction application stage. The first two stages may need to be repeated.ARIMA模型的识别就是判断p,d,q,sp,sd,sq的阶,主要依靠自相关函数(ACF)和偏自相关函数(PACF)...
Stationarity, as modified with differences, is a crucial aspect of ARIMA modeling. In a stationary time series, the mean, variance, and autocorrelation structure remain constant over time. Non-stationary time series, on the other hand, exhibit trends, seasonality, or other changing patterns. ARIMA...

As its name indicates, the acronym ARIMA integrates Autoregression and Moving Average models into a single model depending on the parameters passed. These two ways of modeling change throughout the time series are related but have some key differences. In an autoregression model, we forecast the ...

ARIMA modeling is generally inadequate for long-term forecastings, such as more than six months ahead, because it uses past data and parameters that are influenced by human thinking. For this reason, it is best used with other technical analysis tools to get a clearer picture of an asset's...
