NettetTime series models are used to forecast events based on verified historical data. Common types include ARIMA, smooth-based, and moving average. Not all models will yield the same results for the same dataset, so it’s critical to determine which one works best based on the individual time series. In time series analysis, the moving-average model (MA model), also known as moving-average process, is a common approach for modeling univariate time series. The moving-average model specifies that the output variable is cross-correlated with a non-identical to itself random-variable. Together with the autoregressive (AR) model, the moving-average model is a special case and key component of the more general ARMA and ARIMA models of time series, which have a more …
