Dear all,
in order to analyse the seasonal component and the trend of a time series,
I'm using loess for a local regression. In particular I'm using the command
"loess.smooth", which gives automatically a vector with the results after
the smoothing. My problem is that I have to multiply the neighborhood
weigths, used inside the loess procedure, by robustness weigths, but the
command "loess.smooth" can't accept these robustness weigths.
Does somebody know how could I do to insert them ?

Thanks in advance
