Dear members, I'm trying to do a local polynomial estimation where the weight function is the inverse of the kernel (using a gaussian kernel). Does anybody know how I can do it? When I work with a weigth function usual I use: locfif(y~lp(x,deg=1,h=0.75),kern="gauss") Does anybody know how I can state the inverse of the kernel function this case? Thanks a lot [[alternative HTML version deleted]]
