Re: [R] How to do goodness-of-fit diagnosis and model checking for rlm in R?

Thanks a lot Bert. Yet still, I would like to know does the diagnosis and model-checking for rlm follow the same procedure as lm ... Thank you! On Fri, Jul 6, 2012 at 9:27 AM, Bert Gunter wrote: > > > On Fri, Jul 6, 2012 at 7:19 AM, Michael wrote: > >> Hi all, >> >> I am reading the MAS

[R] How to do goodness-of-fit diagnosis and model checking for rlm in R?

Hi all, I am reading the MASS book but it doesn't give examples about the diagnosis and model checking for rlm... My data is highly non-Gaussian so I am using rlm instead of lm. My questions are: 0. Are goodness-of-fit and model-checking using rlm completely the same as usual regression? 1.
