A Research on Linear Combined Forecasting Model for Instrument Precision
The weigh-optimized linear combined method (WOLC) and non-negative time-variant weights combined method (NTVW)were employed to combine ARMA with BP neutral network (BPNN), and compared the forecasting result with the result of ARMA and BPNN. The forecasting result indicated that combined forecasting methods could be applied to the changing law forecasting of the precision of standard instrument, make full use of advantages of each forecasting method, and have better effect on the forecasting precision. The result showed that the time-variant method had many advantages over fixed weight combined method.
