eugene is a generalized simulator for outbreaks based on the work of Riou & Althaus (2020). The primary goal is to probe two of the parameters that describe the epidemic of COVID-19, the basic reproduction number \(\mathcal{R}_0\) and the overdispersion factor \(k\). We take an Approximate Bayesian Computation approach to estimating \(\mathcal{R}_0\) and \(k\) by running thousands of stochastic outbreak simulations and exploring which values of \(\mathcal{R}_0\), \(k\), and other parameters accurately reproduce the incidence of COVID-19 on January 18, 2020.
