Analysis of the main factors affecting the number of COVID-19 deaths

ABSTRACT

This paper focuses on the main factors affecting the number of COVID-19 deaths. By correlation analysis, the number of people vaccinated and the number of infection cases are the main factors of the number of deaths. A prediction model on the number of deaths using these factors and linear regression is therefore built. The model was next used to predict and compare the number of COVID-19 deaths with actual data in several countries. Additional influences were further analyzed for countries with poor fits. © 2022 SPIE
