Monitoring the return to normality in six European countries IV: the persistence of a fat tail

Abstract

During the end-week of this Note, France, once again, changed completely its original data, especially the daily new cases information. As a result, analysis of the new cases’ ratios has been completely disturbed, while the last results display very high values, probably meaningless, making it impossible to say something about the decline of the epidemic. Revisions had already occurred1, as well as with the daily deaths statistics, recently plagued with outliers and negative values.
