A least-squares prediction filter is a special case of the least-squares filter. In this case, the desired output is a time-advanced version of the input signal. The design of a least-squares prediction filter requires only the autocorrelation of the input signal. Least-squares filtering, as a mathematical process, does not require a detailed description of the signals involved. That aspect makes least-squares filtering very useful.
