SIR models are a type of compartmental model in epidemiology. They divide the population into three compartments:
Susceptible (S): Individuals who have not yet been infected but are at risk. Infected (I): Individuals who are currently infected and can spread the disease. Recovered (R): Individuals who have recovered from the disease and are assumed to be immune.
The transitions between these compartments are governed by rates that define how quickly individuals move from one compartment to another.
