We present a model for estimation of temperature effects on mortality that is able to capture jointly the typical features of every temperature-death relationship, that is, nonlinearity and delayed effect of cold and heat over a few days. Using a segmented approximation along with a doubly penalized spline-based distributed lag parameterization, estimates and relevant standard errors of the cold- and heat-related risks and the heat tolerance are provided. The model is applied to data from Milano, Italy.
我们提出了一个用于估计温度对死亡率影响的模型,该模型能够共同捕捉每种温度与死亡关系的典型特征,即非线性以及寒冷和炎热在数天内的延迟效应。通过分段近似以及基于双惩罚样条的分布滞后参数化,给出了与寒冷和炎热相关风险以及耐热性的估计值和相关标准误差。该模型应用于意大利米兰的数据。
