| Abstract: | Constructed an optimal DGM(2,1)mathematical model on grain production with an application of the grey theory,through the integrated information of the vibration sequence of Nanyang total grain yield.An optimal DGM(2,1)model can achieve much better results than the conventional one in forecast,prediction accuracy and applicability can be further improved.Based on this model,made a prediction of Nanyang total grain yield from 2009 to 2013,provided scientific and theoretical basis for the relevant departments ... |
