Fig. 1From: Assessing parameter identifiability in compartmental dynamic models using a computational approach: application to infectious disease transmission modelsModel 1: Simple SEIR – Population is divided into 4 classes: susceptible (S), exposed (E), infectious (I), and recovered/removed (R). Class C represents the auxiliary variable C (t) and tracks the cumulative number of infectious individuals from the start of the outbreak. This is presented as a dashed line, as it is not a state of the system of equations, but simply a class to track the cumulative incidence cases; meaning, individuals from the population are not moving to class C. Parameter(s) above arrows denote the rate individuals move between classes. Parameter descriptions and values are found in Table 1Back to article page
