Enlightening remarks here: http://www.stata-journal.com/article.html?article=st0173
and software available using -findit mmregress-
I almost used -mmregress- in real life recently, but it turned out that the data were ill-conceived (the authors had created an outcome variable that was a ratio which was no better behaved than you would expect) and I ended up analysing it without invoking M-estimators.
