Dear R family, I want to calculate the joint probability (distribution) of two random continuous variables X and Y. Could to please tell me how to do it?Thanks in advance.. elisa [[alternative HTML version deleted]]
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
