A function that computes the likelihood of a set of parameters.

A function that computes a measured system property given a current (time t) and previous (time t-1) system state.

An ordinary differential equation that may require fixed or free parameters, the current time t, the current response value, and / or external environmental time series.

A function that returns a parameter's current value by its name.

Paired time-series representing the true and modelled time-series.
