I have a simulation question...
(not related to stata, but I need feedback 
from those familiar with this).
I have a time series [X(t),t=1,N]
I know the mean E(x) and Variance V(X).
I want to simulate/generate a time series
[Y(t), t= 1,N] such that
mean = E(Y) (specified) 
variance = V(Y) (specified)
correlation = R (specified)
In other words, Y is a new simulated series 
correlated to X by a factor R.
Any help/guidance will be greatly appreciated.
