针对相互影响的多变量非等间距原始数据序列的模拟预测问题, 对多变量MGM(1, m)模型在非等间距情形下进行建模, 建立了非等间距MGM(1, m)模型, 以提高模拟预测精度.应用实例表明了非等问距MGM(1, m)模型较各个变量建立单变量非等间距GM(1, 1)模型的模拟预测精度有显著提高.该模型适于等间距和非等间距建模, 使非等间距建模具有更广泛的应用价值

Based on the problem of simulation and prediction of the non-equidistant raw data series for the multi-variable with interaction, the multi-variable MGM(1, m) model in the case of non-equidistance is modeled and the non-equidistance MGM(1, m) model is constructed in order to improve the accuracy of simulation and prediction. The simulation and prediction accuracy is proved to be higher in multi-variable non-equidistant MGM(1, m) model than in single-variable nonequidistant GM(1, 1) models according to an application. The proposed model is suitable in non-equidistant modeling and equidistant mo...
