| 摘 要： | 目的：探讨确定疾病空间分布趋势面模型阶次的方法。方法：通过分析趋势面模型和线性回归模型的关系，评价确定趋势面模型阶次的多种方法的适用性。结果：讨论了趋势面模型与线性回归模型的区别，提出了确定趋势面模型阶次的5种方法：直接判定法、拟合优度判定法、剩余均方判定法、逐次F检验判定法、样本穿插二分判定法。结论：根据疾病地理流行病学原理，应综合应用上述各种判定方法的结果确定趋势面模型阶次。

| Abstract: | Objective:To explore the order-selecting methods for trend surface model of spatialdistribution of disease.Methods:Based on the geographical epidemiology of disease,we researched therelationship between the linear regression model and the trend surface model,and explored the order-selecting method for trend suface model.Results:There were many differences between the linearregression model and the trend surface model,and according to these differences,we put forward thefollowing five methods to select the order of trend surface model:method based on geographicalepidemiology of disease,R~2,residual mean square,F-test order by order,and interlacing with two groupsof sampling points in the same area.Conclusion:For the practice of trend surface analysis,we shouldunite the above five order-selecting methods to select the order of trend surface model exactly. |
