minimizer: Minimize the negative log likelihood

In nwfsc-assess/nwfscAgeingError: Estimating ageing error with 'TMB' from double reads

Minimize the negative log likelihood

Description

Minimize the negative log likelihood using "nlmimb" and/or "optim".

Usage

minimizer(
  model,
  method = c("optim", "nlmimb", "both"),
  lower,
  upper,
  verbose = FALSE
)

Arguments

model	A model to be optimized.
method	A string specifying the desired method to be used for the optimization routine. The options are listed in the function call, where the default is to use "optim". Using both routines is an option, via "both", and will lead to first optimizing the model using "nlminb" and then re-optimization of the model with "optim". Note that when using stats::optim(), the "L-BFGS-B" method is used rather than the default method of "Nelder-Mead".
lower, upper	Vectors of parameter bounds of the same length as the number of parameters in the model.
verbose	A logical specifying if messages should be printed. The default is to NOT print, i.e., verbose = FALSE.
