WebbFor a stationary time series, a moving average model sees the value of a variable at time ‘t’ as a linear function of residual errors from ‘q’ time steps preceding it. The residual error is calculated by comparing the value at the time ‘t’ to moving average of the values preceding. Mathematically it can be written as − Webb20 dec. 2024 · The Moving Average method is very simple in comparison to the least squares method. 2.

The moving-average model specifies that the output variable is cross-correlated with a non-identical to itself random-variable.
