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.
