Dear friends,
Suppose the correlation matrix of x1-x3 is as follows:
x1 x2 x3
x1 1
x2 0.5 1
x3 0.6 0.4 1
1.First, to generate the matrix of x1-x3 in R;
2.to get the random number: x1<-rnorm(10), is it enough to generate only the
x1-values? Do i need to generate x2 and x3?
3. y=x1+2*x2+3*x3 , to generate the y-values;
Thanks very much!
