i want to change the "robustness weights" used by loess. these
are described on page 316 of chambers and hastie's "statistical models in S"
r_i = B(e_i,6m)
where B is tukey's biweight function, e_i are the residulas, and m is the
median average distance from 0 of the residuals. i want to
change 6m to, say, 3m.
is there a way to do this? i cant figure it out from the help files.
