Simple moving average in time series

WebbIn statistics, a moving average ( rolling average or running average) is a calculation to analyze data points by creating a series of averages of different selections of the full … 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 comp…
