2. 输入程序

[plain] view plain copy print ?

library(rgl)
library(MASS)
library(evd);
data(lossalae)
U=rand(lossalae[,1]+rnorm(nrow(lossalae),mean=0,sd=.001))/(nrow(lossalae)+1)
V=rank(lossalae[,2])/(nrow(lossalae)+1)
M=kde2d(qnorm(U), qnorm(V), n=35)
persp3d(M$x, M$y, M$z, col='green',xlab="loss", ylab="alae", zlab="")
