Basic SEIR 4. What is the equation that describes Ro for this model? 5. Compare the dynamics of the SIR and SEIR models by running both with the same transmission rate, 3, recovery rate, y and population size. Then, vary the parameter o. How does the introduction of the E class and the length of the incubation period change the resulting epidemic? Consider the timing and magnitude of peak caseload, as well as the proportion of the population that is infected by the end of the epidemic. 6. Run the model with values: N = 500, 8 = 0.02, o = 0.2 and y = 0.1. How many people have become, or are currently, sick by day 20? On what day does the epidemic peak?
