outterobj_lkh {pCODE} | R Documentation |
An objective function of the structural parameter computes the measure of fit.
outterobj_lkh(ode.parameter, basis.initial, derivative.model, likelihood.fun, inner.input)
ode.parameter |
Structural parameters of the ODE model. |
basis.initial |
Initial values of the basis coefficients for nonlinear least square optimization. |
derivative.model |
The function defines the ODE model and is the same as the ode.model in 'pcode' |
likelihood.fun |
The likelihood or loglikelihood function of the errors. |
inner.input |
Input that will be passed to the inner objective function. Contains dependencies for the optimization, including observations, penalty parameter lambda, and etc.. |
neglik The negative of the likelihood or the loglikelihood function that will be passed further to the 'optim' function.
