Usage
optimizerNlm(start, objective=objectiveML, gradient=TRUE,
maxiter, debug, par.size, model.description, warn, ...)
optimizerOptim(start, objective=objectiveML, gradient=TRUE,
maxiter, debug, par.size, model.description, warn, method="CG", ...)
optimizerNlminb(start, objective=objectiveML, gradient=TRUE, maxiter,
debug, par.size, model.description, warn, ...)
Arguments
start
a vector of start values for the parameters.
gradient
TRUE
if an analytic gradient is to be used (if one is available).
maxiter
the maximum number of iterations allowed.
debug
TRUE
to show the iteration history and other available information about the optimization.
par.size
"startvalues"
to have the optimizer scale the problem according to the magitudes of the start values (ignored by optimizerNlminb
).
model.description
a list with elements describing the structural-equation model (see the code for details).
warn
if FALSE
, suppress warnings during the optimization.
method
the method to be employed by the optim
optimizer; the default is "CG"
(conjugate-gradient). ...
additional arguments for the nlm
, optim
, or nlminb
optimizer.
