Autoregressive integrated moving average - Wikipedia
Autoregressive integrated moving average. In time series analysis used in statistics and econometrics, autoregressive integrated moving average (ARIMA) and seasonal ARIMA (SARIMA) models are generalizations of the autoregressive moving average (ARMA) model to non-stationary series and periodic variation, respectively.

autoregressive. The (AR) model is one of the foundational legs of ARIMA models, which we’ll cover bit by bit in this lecture. (Recall, you’ve already learned about AR models, which were introduced all the way back in our first lecture) Precisely, an AR model of order. 0 p. , denoted AR( ), is of the form. p.
Chapter 1: AutoRegressive Integrated Moving Average (ARIMA)
ARIMA, or AutoRegressive Integrated Moving Average, is a set of models that explains a time series using its own previous values given by the lags (AutoRegressive) and lagged errors (Moving Average) while considering stationarity corrected by differencing (oppossite of Integration.) In other words, ARIMA assumes that the time series is ...
