rodeoEstimate: Estimate parameters

In dkneis/knut: Kneis utilities

Description

Estimates parameters using modFit from the FME package.

Usage

rodeoEstimate(inMod.guess, inMod.lower, inMod.upper, lst_inFix, model, lst_obs,
  extract, transf)

Arguments

inMod.guess	Initial guess of the parameters / initial values to be optimized. Named numeric vector.
inMod.lower	Lower bounds of the parameters / initial values to be optimized. Named numeric vector.
inMod.upper	Upper bounds of the parameters / initial values to be optimized. Named numeric vector.
model	Object of class rodeo.
extract	A function that extracts simulated data from the output matrix of simul. It should return a matrix of dimensions nt * nv where nt is the number of model output times and nv equals the number of value columns in obs, i.e. excluding the time column. Typically, the function selects a specific column (or multiple colums) from the original output matrix of the ODE solver or it computes new column(s) from the original ones (e.g. the sum of two state variables).

Value

A list with the following components:

• estimates Named vector of the estimated parameters.

• stdErrors Named vector of the parameters' standard errors.

• residuals Numeric vector of residuals (e.g. for calculation of RMSE).

• info Return code of optimizer. See help for summary.modFit.

Note

See notes for compare.
