Example of stratifying within in compartmental modelling: Behaviour was modelled in two ways: an increase in the proportion of the population vaccinated led to an increase in non-compliance of preventative measures, and an increase in deaths resulted in an increase in compliance of preventative measures. Susceptible (S) and vaccinated (V) compartments also had susceptible and vaccinated non-compliant compartments (SNC, VNC, respectively)
