基于Logistic拟合的COVID-19流行病结局预测及其可靠性估计

COVID-19 epidemic outcome predictions based on logistic fitting and estimation of its reliability

Dávid Tátrai, Zoltán Várallyay

摘要:

自2019年底首次爆发COVID-19疫情以来,全球所有国家的感染人数、死亡人数和康复人数均已获得数据,这些数据可用于统计分析。本文的主要兴趣是假设测试过程的方法,即数据收集方法和社会行为不会随着时间的推移而改变,logistic方程可以在多大程度上预测世界任何地区的COVID-19疫情结果。除了社会相关性之外,这项研究还有两个科学目的:我们调查简单的饱和模型是否可以描述COVID-19流行的趋势,如果可以,我们想确定在流行期间的哪个点拟合参数提供可靠的预测。我们还根据逻辑模型和2020年3月27日的可用数据对几个国家的疫情结果进行了估计。基于中国的饱和情况,我们设法找到了一些标准来判断预测的可靠性。

英文摘要:

Since the first outbreak of the COVID-19 epidemic at the end of 2019, data has been made available on the number of infections, deaths and recoveries for all countries of the World, and that data can be used for statistical analysis. The primary interest of this paper is how well the logistic equation can predict the outcome of COVID-19 epidemic in any regions of the World assuming that the methodology of the testing process, namely the data collection method and social behavior is not changing over the course of time. Besides the social relevance, this study has two scientific purposes: we investigate if a simple saturation model can describe the trend of the COVID-19 epidemic and if so, we would like to determine, from which point during the epidemic the fitting parameters provide reliable predictions. We also give estimations for the outcome of this epidemic in several countries based on the logistic model and the data available on 27 March, 2020. Based on the saturated cases in China, we have managed to find some criteria to judge the reliability of the predictions.
