Medical Definition of Discrete time model
1.
A model in which the system jumps from one state to the next at fixed intervals or timesteps. These difference models are simple to understand but often difficult to analyse; Contrast continuous time models.
The parameters in such a model refer to the amount of change over the finite timestep; they are sometimes referred to as finite rates.
In a (rather precise) sense, a differential equation is what you eventually get from a difference equation when you let the timestep get smaller and smaller and smaller.
