Nature of problem:
The program either smoothes a statistical series with a strongly non- stationary (e.g. resonance-like) trend or extracts from it a low frequency envelope from below.
The high and low frequency filters sought for, are constructed as solutions of the problem of minimization of oscillation or variability measures and distances of the functions from the initial series. The resulting difference equations are solved by a method, which is fast and compact with respect to the computer memory.
