| 摘 要： | 目的：了解辽阳市辽阳县恶性肿瘤死亡情况，介绍GM(1,1)模型预测辽阳市辽阳县恶性肿瘤死亡率。方法收集辽阳市辽阳县2008-2015年恶性肿瘤死亡数据，并应用GM(1,1)模型对其进行动态预测。结果 GM(1,1)预测模型为x^(1)k+1=(x1(0)-μ/α)e-αk+μ/α=6315.220.023Ik-6177.06，预测精度优，预测2016年和2017年辽阳市辽阳县恶性肿瘤死亡率分别为173.50/10万和177.55/10万。结论 GM(1,1)模型能够用于恶性肿瘤死亡率预测。

| Abstract: | Objective To comprehend the mortality of malignant tumors in Liaoyang County and to predict it with GM(1,1) model. Methods The data of the mortality of malignant tumors in Liaoyang County from 2008 to 2015 were col-lected and predicted with GM(1,1) model. Results It showed the GM (1,1) prediction model was x^(1)k+1=(x1(0)-μ/α)e-αk+μ/α=6 315.220.023Ik-6 177.06, and the model was advanced by the precision-test. The predictive values of the mortality of ma-lignant tumors were 173.50/100 000 and 177.55/100 000 respectively during 2016 and 2017. Conclusion The GM(1,1) model can be applied to predict the mortality of malignant tumors. |
