Subject: [R] Simulate data based on correlation coefficient
Hello all,
I have a vector with 1000 values and I would like
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)

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.
