Specifically, an ARIMA (autoregressive integral moving average) model is a time series prediction method that models and predicts based on historical data of the time series itself.
The ARIMA model consists of three parts: autoregressive (AR), differential (I), and Moving Average (MA): autoregressive (AR): the part represents the effect of the value of the past moment of the time series on the value of the current moment. I.e. when the value of the past moment has an effect on the value of the present moment, we call it to have an autoregressive property, denoted AR (p), where p is the order of the autoregressive term. Difference (I): this section represents the degree to which the time series is differentiated so that the time series becomes smooth. The stationary time series can be modeled and predicted more easily. Typically using first or second order differential. If we do not need to do any differencing, the model is called ARIMA (p, 0, q). Moving Average (MA): this part represents the effect of the error in the past moment of the time series on the current moment value. I.e. when the error of the past moment has an effect on the value of the present moment, we call it of a moving average nature, denoted MA (q), where q is the order of the moving average term.
ACF: the autocorrelation function (autocorrelation function) is a function describing the correlation between observations of the same time series at different points in time. It is a direct measure of the time series that can be used to detect if the time series has an auto-correlation or an order of a correlation model.
ADF: the unit root test (Augmented Dickey-Fuller test), also known as the "Augmented Diety-Fuller test", is a common method for checking whether a time series has a unit root (i.e., stationarity). ADF verification may help us determine whether time series need to be differentially processed to plateau or may be used to select the appropriate time series model.
