Why is it important?

The findings show noticeable and increasing measurement errors in the three official datasets as the pandemic outbreak expanded, and more countries contributed data for the official repositories, raising data comparability concerns and pointing to the need for better coordination and harmonized statistical methods.


We wanted to study the COVID-19 pandemic and its economic and financial effects. Before starting a statistical analysis and modeling, we had to know the amount of measurement error in our data. We wanted to avoid garbage in, garbage out. This article is the result of this stage of the research, and we hope it can help other researchers to use our COVID-19 combined dataset and dashboard with minimum systematic measurement errors.
