Stochastic Modelling of Coronavirus spread

The podcast discusses stochastic models for infectious diseases, contrasting them with deterministic models. It recaps the compartmental framework (SIS and SIR models) and explains stochastic counterparts, focusing on continuous-time models. The discussion covers the chain binomial approach, stochastic processes, and the Kolmogorov forward equation, including its representation in matrix form. It also explores generating functions, characteristic functions, and the derivation of a partial differential equation (PDE) for the moment generating function. The podcast extends the discussion to the SIR model, highlighting the similarities and differences compared to the SIS model and setting the stage for introducing networks into the framework in the next episode.
