5. The cyclicality of the new cases of the virus
First interpretation leads to a
question: why do we not study
the same thing for specific
countries ?
7 days
6. The key of the analysis: the ratios
Summing all rows per week number
Summing all rows per country
Time analysis (Plotly)
Location analysis (Choropleth map)
7. Problematic of the analysis
● To what extent ratios impact the location of the virus in the world ?
● To what extent ratios evolve through the time ?
8. Methods
● R studio
● Time Series packages (zoo, xts)
● Data visualization packages (plotly, leaflet)
● First the whole world, then specific cases (countries)
● First the whole period, then 2 months
14. Difference between countries
● Such differences are due to certain unique parameters such as
- Total population
- Measures taken
- Amount of tests done
- Culture
- HDI
15. Difference over time
● Geographical impact:
- USA 8x more cases than UK and France (late March)
- USA more marked peak (48925 cases on April 26th)
● Impact on cyclicality:
- The difference between weekdays and weekend depends on the period
we looked at. For example, in April and May 2020 in France, the lockdown
made the data less seasonal than the one for UK for example.
