报告摘要:Since the outbreak of the new coronavirus disease (COVID-19) in December 2019, a large number of scientific studies and data analysis reports have been published in the international journal of medicine and statistics. Taking the estimation of the incubation period as an example, we propose a low-cost method to integrate multiple research results and available data. By using empirical likelihood method, we can effectively incorporate summarised information even if it may be derived from a misspecified model. Considering the possible uncertainty in summarised information, we augment a logarithm of the normal density in the log empirical likelihood. We show that the augmented log-empirical likelihood can produce consistent estimates for the underlying parameters. Moreover, the Wilks' theorem holds to be true. We illustrate our methodology by analyzing a COVID-19 incubation period data set retrieved from Zhejiang Province and summarised information from a similar study in ShenZheng, China.
