Pre-process: arguments for optimization function
preprocess.optim(
x,
method = c("L-BFGS-B", "newuoa"),
select_eta = NULL,
control = list(),
force_initial_eta = NULL,
quantile_bound = 0.001
)a list of named arguments passed to optimizer (i.e. arg.optim)
the model object
optimization method; the default is "L-BFGS-B" (from stat::optim()), alternatively "newuoa" for minqa::newuoa()
a vector of numeric values, the numbers of the ETAs to be estimated (default is NULL, all ETAs non-equal to zero)
a list passed to the optimizer (see stats::optim() or minqa::newuoa() documentation)
a vector of numeric values to start the estimation from (default to 0 for "L-BFGS-B")
a numeric value representing the quantile of the normal distribution admitted to define the bounds for L-BFGS-B (default is 0.001, i.e. 0.1%)
