[R] joint probability distribution

[Rui Barradas]

Hello,

You need to be much more specific. What do you know about the 
distributions of X and Y? And about their joint distribution?

If you suspect the joint distribution to be a bivariate normal try 
package mvtnorm with

mu <- c(mean(x), mean(y))
sigma <- cov(cbind(x, y))


You can also try kernel density estimates:

library(sos)
findFn('kde')


Hope this helps,

Rui Barradas
