非等间隔灰色预测模型的二次优化
Re-optimization of non-equilditant gray model
摘要
Abstract
In order to improve the prediction accuracy of non-equilditant sequence data,this paper used a new weighted method of non-equilditant sequence data and turned it into the equal interval series.Based on this,the model of initial conditions adaptive optimization function was used to quadratic optimization,and finally grey forecasting model was obtained.And this model used for modeling,analysis,prediction and calculation of squared residuals and average MSE with the actual measured data,and comparing the accuracy of this model and other models.The results show that the model in the non-equilditant sequence data processing has better prediction accuracy.关键词
