The standard SIR model

The standard SIR model is a compartmental model where a constant sized population is split into the compartments

• S - susceptible to infection
• I - infected and infectious
• R - recovered and immune to re-infection

These variables are then used to form three ordinary differential equations. Farr's Law is satisfied by an imbalance between logistic growth and exponential decay.
