Title: Research on Characteristics of Grey Verhulst Model Based on Multiple Transformation
Abstract: Multiple transformation is made for the data series of grey Verhulst model.The least square estimate method is used in order to get parameters series of multiple transformation.Through a series of mathematical formula caculation,the change of multiple transformation on parameters characteristics of the model is analyzed,and the effect of simulation and prediction values and the relative error of the transformed model are discussed.Research results show that the model simulative and predicative results do not change,while the magnitude of the datas is also reduced and the modeling process is simplified,when the original data series is transformed by multiple transformation.The results for the further system study of grey Verhulst model are of great significance.Finally,the validity and the practicality of characteristics research on the Verhulst model is proved by a real project.
