Deterministic model

The average measure (e.g., rates) of a system (e.g., populations) is described without randomness; in other words, the outcome is fixed (compare Stochastic model)….

Mechanistic model

Describes real-world interactions pertaining to infection transmission, pathogenesis, and measures of control such as vaccination (compare Phenomenological model)….

Pair model

A type of compartmental models describing formation and dissolution of pairs (i.e., couples) in a population. Usually used to model sexually transmitted infections, pair models can account for time spent…

Stochastic model

In contrast to deterministic models, stochastic models have random components; parameters or variables could be random (i.e., can be represented with a probability distribution)….

Theory‐driven model

Builds upon assumptions or existing knowledge about relationships (e.g., effectiveness of an intervention) (compare to data-driven model).
