p-values of coefficients of national factors with $\mathsf{\alpha }$ and $\mathsf{\gamma }$. Population, annual precipitation, pharmaceutical sales, and imports to GDP ratio were statistically significant with $\alpha$, the number of maximum predicted confirmed cases (A,C). Age-related factors, population, percentage of malnourished population, life expectancy, temperature, etc. were significantly related with $\gamma$, rate of spread of COVID-19 (B,D) (see Figure S8 for the relationship of national factors with $\beta$).
