The R program creates the PNG file:
library(np)
library(mlbench)
data(BostonHousing)
s <- sort(BostonHousing[,13], index.return=T)
x <- BostonHousing[s$ix,13]
y <- BostonHousing[s$ix,14]
lr <- lm (y~x)
nw <- npreg(y~x)
nw2 <- npreg(y~x, bws=nw$bw/3)
nw3 <- npreg(y~x, bws=nw$bw*3)
png("NW.png")
plot(x, y, xlab="Anteil der Unterschichtbevölkerung pro Bezirk (in %)", ylab="Mittlerer Hauspreis pro Bezirk (in 1000 US$)", main="Boston Housing Daten", cex=0.5)
abline(lr, lwd=2)
lines(x, fitted(nw), lwd=2, col="red")
lines(x, fitted(nw2), lwd=2, col="blue")
lines(x, fitted(nw3), lwd=3, col="green")
