摘要
针对灰色预测模型自身的不足,提出利用平滑处理技术解决原始数据离散度大的方法,对残差进行线性回归建模,并修正预测结果。验证实例表明改进后的预测模型可有效提高预测的精度。
Lack of gray prediction model,the smooth processing technology to solve the original data dispersion method,linear regression modeling and prediction results corrected residuals,tests showed that improved the forecasting model can effectively improve the prediction accuracy.
