THE RESIDUAL CORRECTING PREDICTION OF GREY MODEL FOR MALARIA CASES IN CHINA

  • Online:1993-11-30 Published:2017-01-06

摘要: 根据1986—1990年我国疟疾发病资料,应用灰色系统方法,建立灰色 GM(1,1)模型。为了提高模型精度,对原模型进行残差修正,建立残差校正灰色 GM(1,1)模型,结果表明后者较原模型精度有了很大提高,并且 1991年疟疾发病人数的预测结果(101 770例)和实际发病人数(101636例)是符合的。

Abstract: In this study a grey model GM(1,1) was developed on the basis of malaria cases reported for the period of 1986-1990 in China. In order to further enhance the predicting power of the model,residual correction is performed and the residual correcting GM(1,1)model was established. The result showed that the predicting performance of the latter model was much improved. The number of predicted cases for 1991(101 770) was conformed to the number of actual malaria cases reported (101 636).
