论文摘要
新型感染剂的出现给疾病传播的统计模型带来了挑战。这些挑战来自有限的,质量较差的数据和对代理商的不完全理解。此外,由于各种因素,各个地区的爆发表现出不同的表现,因此必须将模型考虑区域细节。在这项工作中,我们提供了一个模型,该模型有效利用受限的数据资源来估计地方一级的疾病传播率,尤其是在早期爆发阶段,主要是感染计数和汇总的局部特征。该模型将基于每日感染数量的病原体传播方法与回归技术合并,在疾病传播与局部地区因素(例如人口统计学,健康政策,行为,甚至气候)之间取得相关性,以估计和预测每日感染。我们合并了准得分方法和一个错误术语,以浏览潜在的数据问题和错误的假设。此外,我们介绍了一个在线估计器,该估算器促进了实时数据更新,并以迭代算法进行参数估计。当数据质量次优时,这种方法促进了疾病传播的实时分析,并且对感染性病原体的了解受到限制。它在爆发的早期阶段特别有用,为当地决策提供了支持。
The emergence of novel infectious agents presents challenges to statistical models of disease transmission. These challenges arise from limited, poor-quality data and an incomplete understanding of the agent. Moreover, outbreaks manifest differently across regions due to various factors, making it imperative for models to factor in regional specifics. In this work, we offer a model that effectively utilizes constrained data resources to estimate disease transmission rates at the local level, especially during the early outbreak phase when primarily infection counts and aggregated local characteristics are accessible. This model merges a pathogen transmission methodology based on daily infection numbers with regression techniques, drawing correlations between disease transmission and local-area factors, such as demographics, health policies, behavior, and even climate, to estimate and forecast daily infections. We incorporate the quasi-score method and an error term to navigate potential data concerns and mistaken assumptions. Additionally, we introduce an online estimator that facilitates real-time data updates, complemented by an iterative algorithm for parameter estimation. This approach facilitates real-time analysis of disease transmission when data quality is suboptimal and knowledge of the infectious pathogen is limited. It is particularly useful in the early stages of outbreaks, providing support for local decision-making.
