| Abstract: | Studies are presented to evaluate the accuracy and efficiency of the time-series extrapolation decisions made with the use of an interactive graphical system GRAFFECT. This tool facilitates the decomposition of the extrapolation task by permitting the serial decomposition of cue data. The extrapolation task included trend modelling and extrapolation, seasonal pattern modelling, extrapolation from the noise residual series. The ultimate forecast is produced by automatic decomposition of judgementally determined components. GRAFFECT uses an interactive graphical interface controlled with a mouse. |
