Subject: [RsR] Update of nlrob.*() (0.0.2) for robust nonlinear regression
Hi all,
You can download the 0.0.2 update of the nlrob.*() functions from:
https://www.dropbox.com/s/yp1nza8twalf9r6/nonlinrobreg_0.0.2.zip
Requires packages: PolinomF, robustbase (>= 0.9-8), ggplot2
= Changes =
nlrob.tau(): Added the bisquare psi function which is now the default.
(Does anyone know if the tau-estimator has been defined in the literature using other psi functions besides the bisquare and optimal ones?)
nlrob.CM(): Now any of the psi functions in package robustbase can be used. Notice, however, that default values for the tuning constants are provided *only* for the bisquare function.
= Running the example =
source(deopt.R)
source(nlrobreg.R)
# run the code from the example file example_nlrobreg.R
