> Good evening,I am Marta Colombo, student of "Politecnico di Milano". I'm studying Local Regression Techniques such as loess, smoothing splines and kernel smoothers. Choosing "symmetric" for the argument "family" in loess function it is possible to produce a robust estimate , in function smooth.spline and ksmooth I didn't find this possibility. Well, is there a way to produce a robust estimate using smoothing splines or kernel smoothers? And if the answer is no, why? I'm asking these questions because I need to know loess' advantages and disadvantages compared to other techniques. Thank you very much for attention,
