We provide schematics for different parts of the model outlined here. These are useful because they clarify how different model objects, including data and parameters, are related to one another.
Figure 2.1 illustrates a complete observational model, and in particular details the model for multipliers \(\alpha_t\). Figure 3.1 presents the basic infection model, and also shows the GLM-style model for reproduction numbers \(R_t\). Finally Figure 4.1 shows treating latent infections as parameters.
All mathematical notation shown in the figures corresponds to that used in the model description article. Each node is outlined in a color corresponding to the type of object considered. These are interpreted as follows.
