The loess smoother first computes the lamda % nearest-neighbours to the target
point,. A tricube kernel , centered at the target point, becomes zero at the
furthest neighbour. The smooth at the target point is the fitted value from the
locally-weighted linear fit, with weights supplied by the kernel (Hastie
&Tibshirani).
Is it possible to see those weights when we employed loess.smooth in Splus and
how does Splus deal with edge effects.
Thank you very much,
