GM (2,1) recursive forecasting model based on equal dimension and new information

GM (2,1) recursive forecasting model based on equal dimension and new information

Aiming at the problem that the solution of GM (2,1) whitening equation affects its prediction accuracy,a new prediction model dubbed GM (2,1) recursive prediction model of equal dimension new information was pro-posed.The model was deduced from the grey differential equation of GM (2,1) mode,which c...
