Description <p> Standard iterative SEIR models remove people from E and I by assuming an average rate, for example:- <p> <pre> I_n+1 = I_n - k₁I + k₂E </pre> <p> This can be replicated in an agent based model by assigning each person a length of time to stay in E and I based on an exponential random number generator, with the means being the inverse of k₁ and k₂. <p> Incidence in a standard iterative model is based on an assumption of homogeneous mixing and an average per capita contact rate. For example:- <p> <pre> S_n+1 = S_n - bS_nI_n </pre> <p> In this agent based model, an infectee has a radius of infection (r), a probability of infecting a susceptible (q) and susceptibles have a probability of becoming infected (p). The iterative model can be replicated by setting r=infinity, q=1 and p=b. <p> The people are moving about in this scenario but it is irrelevant because of the infinite radius of infection. <p> <b>Click Start to run the model...</b
