Correlation between Deaths and Confirmed cases per capita 

As expected larger per capita deaths result in larger residuals where
Resdual=(Observed_deaths-Fitted_deaths),
and
Fitted_deaths = 0.211 x Observed_deaths (from the R2 analysis).
Therefore we also plotted the Relative residuals where
Relative_residual= (Observed_deaths-Fitted_deaths)/Observed_deaths)

We also provide a histogram of the Relative residuals below:

Conclusions

• As of Feb 1, 2021 
  
  • Montenegro followed by the Czech Republic, Slovenia, Luxembourg and. the US had the highest cumulated confirmed cases per capita.
  • In terms of cumulative deaths per capita, Belgium led the way followed by Slovenia, UK, Czech Republic, Italy, Bosnia Herzegovina, Macedonia and the US.
  • Portugal had the highest daily confirmed cases and deaths per capita as of Feb 1s, 2021. However, it had not caught up to the leaders in cumulated cases per capita.
  • In both daily and cumulative cases and deaths per capita, European countries and the US dominate the leading countries, the only outside countries showing up are Lebanon and Israel.
  • As would be expected there is a strong correlation (R² = 0.7679) between deaths and confirmed cases per capita.
  • The worldwide ratio of deaths to confirmed cases is about 2.1% as indicated by the R² trendline between deaths and confirmed cases per capita as of Feb. 1st 2021.
