The command robust in a regression
Web2 I'm using R to compute robust multiple linear regression. I use the command rlm from the package MASS. As psi function I use psi.huber or psi.bisquare. Is there a way to get an estimator of the goodness of fit of the model? Maybe something comparable to the Adjusted R-squared, for the parametric multiple linear regression? WebRATS: robusterrors option is available in many of the regression and optimization commands (linreg, nlls, etc.). Stata: robust option applicable in many pseudo-likelihood based procedures. Gretl: the option --robust to several estimation commands (such as ols) in the context of a cross-sectional dataset produces robust standard errors.
