Fractional Order Accumulation NGM (1, 1, k) Model with Optimized Background Value and Its Application
Aiming at the problem of unstable prediction accuracy of the classic NGM (1, 1, k) model, the modeling principle and parameter estimation method of this model are deeply analyzed in this study. Taking the minimum mean absolute percentage error as the objective function, the model is improved from th...
