| Fitting Segment        
| Defines the bounds (in %) of the intervening segment in the analysis window, usually closer to the end. A signal in the segment is fitted with an estimated model, which, in turn, is used to forecast the signal in the future. The rightmost segment boundary should not be at the zero time in order to avoid side effects of the bandpass filter. The segment boundaries can be adjusted on the signal plot
