The basic assumption of averaging models is that the series has a slow varying mean. Thus, we take a moving average to estimate the current value of the mean and then use this as a forecast for the future. If the series is more or less stable, a lower value of N can be taken.

WebbSlowly varying oscillatory systems occur frequently in physical applications, in both natural and man made systems. The following are some examples. Planetary systems have an obvious oscillatory behavior which may be slowly changing due to various long term effects such as precession, tidal dissipation, or variable mass WebbThe slow variation of the medium is associated with the sphericity of the domain and the latitudinal structure of the zonal wind. Rays along which wave activity propagates, the speeds of propagation, and the amplitudes and phases along these rays are determined for a constant angular velocity basic flow as well as a more realistic jet flow. the orlando health way
