Hello all
I have a feeling this is very simple......but I am not sure how to do it
My boss has two variables, one is an average of 4 numbers, the other is an average of 3 of those numbers i.e
var1 = (X1 + X2 + X3 + X4)/4 var2 = (X1 + X2 + X3)/3
Hello Peter, try the following:
#################################### nsim <- 100 nsamp <- 100
r <- numeric(nsim)
for (i in 1:nsim) {
dat <- matrix(rnorm(4 * nsamp), ncol=4)
v1 <- rowSums(dat)/4
v2 <- rowSums(dat[,1:3])/3
r[i] <- cor(v1,v2)
}plot(sort(r)) ####################################
Hope it helps!
Thomas P.
