D-statistic and quartiles of the developmental index. The figure presents the boxplots of the D goodness-of-fit measure for the cumulative number of confirmed and death cases for the four quartiles of the developmental index. The unit of observation is a country. Smallest, Q2, Q3 and Largest represent the values partitioned by the 25%, 50%, and 75% quartiles of the developmental index. The boxplots represent 25%, 50%, and 75% quartiles of D. The dots represent the mean values. *** and ** indicate significance of the difference in means between the Smallest and the Largest quartile at the 1% and 5% level, respectively.
