Suppose I have a bunch of points {x_i,y_i}, i = 1, ...,M in the plane. I want
to obtain a local weighted estimate of the scatterplot of these points
(such as that you get from lowess()) but in such a way that will be easy to
update the current estimate if I get an additional point {x_{M+1},y_{M+1}}.
Pointers to the literature and ideas are appreciated...
Thanks in advance.
