Parameter Estimation of Non-equidistant GM(1,1) Model Based on the Euler Formula

摘要：

This thesis brings forward a new method to estimate the parameters a and b of non-equidistant GM(1,1) model. It directly calculates the parameters of non-equidistant GM(1,1) model on the basis of Euler formula, which is different from traditional method by constructing the background value. The application case indicates the precision of simulation and prediction by this method is obviously higher. This method is not only suitable in non-equidistant GM(1,1) model, but also in equidistant GM(1,1) model, and has high precision and wide applicability.
