Re: [R] Simulate data based on correlation coefficient

Try this: rnormcor <- function(x,rho) rnorm(1,rho*x,sqrt(1-rho^2)) a <- rnorm(1000,0,1) b <- sapply(a, rnormcor, rho = 0.7) cor(a,b) Joris "Gustavo"

[R] Simulate data based on correlation coefficient

Hello all, I have a vector with 1000 values and I would like to generate other correlated vector, but with different correlation coefficient (for example, r = 0.7). Any ideas how can I do this? Regards, Gustavo. ___
