nlrob.control: Control Nonlinear Robust Regression Algorithms

Description

Allow the user to specify details for the different nonlinear robust regression algorithms in nlrob.

Usage

nlrob.control(method, psi = c("bisquare", "lqq", "welsh", "optimal", "hampel", "ggw"), init = c("S", "lts"),  optimizer = "JDEoptim", optArgs  = list(), ...)

Arguments

method

character string specifying the method

psi

string specifying the psi-function which defines the estimator.

init

for some methods, currently, "MM" only, a string specifying the initial estimator.

optimizer

currently only "JDEoptim" from package DEoptimR.

optArgs

a list of optional arguments to the optimizer. Currently, that is JDEoptim from package DEoptimR.

...

Value

a list with several named components. The contents depend quite a bit on the method.
