get.label

This function produces an expression to label plots from expressions for variables and units and from character strings.

Infer constant and stochastic, time-dependent parameters to consider intrinsic stochasticity of a dynamic model and/or to analyze model structure modifications that could reduce model deficits.
The concept is based on inferring time-dependent parameters as stochastic processes in the form of Ornstein-Uhlenbeck processes jointly with inferring constant model parameters and parameters of the Ornstein-Uhlenbeck processes.
The package also contains functions to sample from and calculate densities of Ornstein-Uhlenbeck processes.
