Table A.1.
Variables employed in the model and their initial conditions. The 16 variables represent the fraction of population of a country being in each of the compartments. The initial conditions are the standard ones usually employed for SEIR-like models, with all the population susceptible except one person already exposed to the virus. They are the same for every simulation and country, except for the country’s population being individuals for Luxembourg, for Austria and for Sweden.
