Dear members,
I was trying to simulate W which is iid and depends on X and Y.
Here are 2 methods:
Method 1:
x<-rnorm(100)
y<-rnorm(100)
w<-rnorm(100, 2x+y,1)
Method 2:
x<-rnorm(100)
y<-rnorm(100)
w<-2x+y+rnorm(100,0,1)
Are these methods comparable?
Since x and y are vectors, the term 2x+y would return a vector. It seems that,
given Method 1, each element of W would come from a different population with
means depending on the value of x and y. Is that true? Or is Method 1 equally
acceptable as Method 2 in creating W?
I'd really appreciate clues to this puzzle! Thanks!
K.
