The R program to create the PNG file:
library(np)
library(mlbench)
data(BostonHousing)
s <- sort(BostonHousing[,13], index.return=T)
x <- BostonHousing[s$ix,13]
r <- -0.01*runif(length(x))-0.005
png("D13.png", width=640, height=480)
hist(x, freq=FALSE, ylim=c(-0.015, 0.07), col="gray", xlab="Anteil der Unterschichtbevölkerung pro Bezirk (in %)", ylab="Dichte", main="Dotplot, Histogramm und Kerndichteschätzer")
d1<-npudens(x, bws=1.5)
lines(x, fitted(d1), col="red", lwd=2)
d2<-npudens(x, bws=1)
lines(x, fitted(d2), col="blue", lwd=2)
d3<-npudens(x, bws=0.5)
lines(x, fitted(d3), col="green", lwd=2)
points(x,r, cex=0.5)
