摘要 针对糖尿病病人生存时间的不确定性及影响因素的复杂性,将模型平均理论引入病人生存时间分析与预测研究,基于糖尿病病人的数据,利用OPT、S-AIC、S-BIC、AIC和BIC 5种方法预测病人的生存时间。研究表明,模型平均方法要比模型选择方法的预测效果更好。 In view of the uncertainty of the survival time of diabetic patients and the complexity of the influencing factors,this paper introduces the model average theory into the analysis and prediction of patients'survival time.The data of diabetic patients are constructed by five methods,namely,OPT,S-AIC,S-BIC,AIC and BIC,and the survival time of patients is predicted.The results show that the prediction effect of model average method is better than that of model selection method.
