Modeling Complex Systems: A Case Study of Compartmental Models in Epidemiology

<div>An SEIR model can be replaced with an SIR model with a nearly identical trajectory. Important characteristics such as the growth rate, reproduction number, herd immunity threshold, and epidemic size will be exactly the same in both models. The following parameters were used to generate this figure.
