Parameters of the model are sampled with Hamiltonian Monte-Carlo using the PyMC3 Python library. We assume that the infection rate can change every week, with a standard deviation that is also an optimized parameter. When new governmental restrictions are enacted or lifted, we include a small prior to the change of the infection rate.
