灰色数列预测模型在传染病死亡率研究中的应用

APPLICATION OF GREY SERIES FORECASTING MODEL IN THE STUDY OF DEATH RATE OF INFECTIOUS DISEASES

应用 GM(1,1)模型 ,根据部份城市地区传染病标化死亡率建立了灰色预测模型。经检验 ,模型拟合精度甚好 。

In this paper, according to the standardized death rate of infectious diseases of the partial cities, the forecasting model of the standardized death rate of infectious diseases was set up with GM(1,1). By checking, the fitting precision of the model is better and the forecasting effect is satisfying. It has certain directive significance in practice.
