Description Specify your ODE Specify loss function Optimise the loss function
This package provide the tools for approximate and exact parameter estimation in ODE models with regularisation via penalisation.
The ode system is specified via the ode
-subclasses: mak
, plk
, rlk
and ratmak
. In creating these you can also specify numerical solver type via solver
and regularisation type of the parameter arguments via reg
. To numerically solve the ODE use numsolve
and to evaluate the ODE field use field
. The differentials of both quantities can also be evaluated.
To specify the loss function use the reg
in the ODE object to control regularisation and opt
to control the observations, their weights and the tuning parameter of the regularisation.
Having an ode
object and an opt
object, there are two methods for estimating the parameters: approximate estimation via inverse collocation methods, aim
, or exact estimation via interior point methods, rodeo
. If desired, call rodeo
on the results from aim
to use the approximate estimates for initialising the exact estimation.
