Fig 4. The shock index allows to compare the response of distinct countries to COVID-19.

For two countries, Italy (left) and New Zealand (right), the time course of the six indices (top) and their convolution into a comprehensive shock index (bottom) is shown, for distinct values of the time window indicating a 19-weeks incremental length of the observational time between February 23, 2020 and August 01, 2021.
