Sažetak
The reaction to and the effect severity on the population of COVID-19 varied across different countries. This indicates that there are country-level factors which influenced the severity COVID-19 effect on the populace. The goal of this research is to determine some of these factors using Our World in Data COVID-19 dataset. The performance of the country is evaluated using excess mortality (EM), while the inputs selected for the analysis are stringency index (SI), population (P), population density (PD), median age (MA), percent of population aged 65 or older (P65), percent of population aged 70 or older (P70), GDP per capita (GDP), percentage of population living in extreme poverty (EP), death rate from cardiovascular diseases (CDR), prevalence of diabetes withing population (DP), percentage of female smokers (FS), percentage of male smokers (MS), availability of handwashing facilities (HWF), hospital beds available per thousand (HB), life expectancy (LE), and human development index (HDI). The inputs are evaluated using Random Forest (RF) algorithm via two metrics Mean Decrease in Impurity (MDI) and Feature Permutation (FP). Results show that the SI is the most influential factor when evaluated using RF.
