It's not often one gets needs to correct Gabor, but no, least median of squares is not the same as least absolute error regression. Take a look at the package robust if you want the lms. url:www.econ.uiuc.edu/~rogerRoger Koenker email[EMAIL PROTECTED]Depar

Hi I am looking for suitable packages in R that do regression analyses using least median squares method (or better). Additionally, I am also looking for packages that implement algorithms/methods for detecting outliers that can be discarded before doing the regression analyses. Although some webs
