Query: On COVID-19 Modelling   This contribution analyzes the COVID-19 outbreak by comparably simple
mathematical and numerical methods. The final goal is to predict the peak of
the epidemic outbreak per country with a reliable technique. This is done by an
algorithm motivated by standard SIR models and aligned with the standard data
provided by the Johns Hopkins University. To reconstruct data for the
unregistered Infected, the algorithm uses current values of the infection
fatality rate and a data-driven estimation of a specific form of the recovery
rate. All other ingredients are data-driven as well. Various examples of
predictions are provided for illustration.
