摘要在这项工作中,在时空疾病映射的背景下,提出了一种综合贝叶斯最大熵(BME)和卡尔曼滤波(KF)的方法,它们增强了各自的优势,克服了它们在时空映射方面的某些弱点。所提出的BME-Kalman综合允许BME使用来自参数回归建模和KF估计的信息,从而增强知识库。应用贝叶斯-卡尔曼合成方法对山东省(中国)2008年5月1日至2009年3月19日手足口病发病时空地图进行了研究。结果表明,BME-Kalman方法表现出很好的回归和预测精度,即使在低发期和极低发期也保持很好的表现,与传统的作图技术相比,BME-Kalman方法提供了更好的分级疾病特征描述,并对未抽样地点的空间分层发病异质性提供了清晰的解释。BME-Kalman方法具有通用性和灵活性,可以根据应用的需要进行修改和调整。
ABSTRACT In this work, a synthesis of the Bayesian maximum entropy (BME) and the Kalman filter (KF) methods, which enhances their individual strengths and overcomes certain of their weaknesses for spatiotemporal mapping purposes, is proposed in a spatiotemporal disease mapping context. The proposed BME-Kalman synthesis allows BME to use information from both parametric regression modeling and KF estimation leading to enhanced knowledge bases. The BME-Kalman synthetic approach is used to study the space-time incidence mapping of the hand, foot and mouth disease (HFMD) in Shandong province (China) during the period May 1st, 2008 to March 19th, 2009. The results showed that the BME-Kalman approach exhibited very good regressive and predictive accuracies, maintained a very good performance even during low-incidence and extremely low-incidence periods, offered an improved description of hierarchical disease characteristics compared to traditional mapping techniques, and provided a clear explanation of the spatial stratified incidence heterogeneity at unsampled locations. The BME-Kalman approach is versatile and flexible so that it can be modified and adjusted according to the needs of the application.
