Moving Average (MA) Models:

Moving average (MA) models are used in time series analysis to describe stationary time series . The MA-models represent time series that are generated by passing the white noise through a non-recursive linear filter .

A moving average model of a random process Math image in discrete time Math image is defined by the following expression:

where
  • Math image are the coefficients of the linear non-recursive filter;

  • Math image is the order of the MA-model;

  • Math image are elements of the (input) white noise;

  • Math image are the output uncorrelated errors.
