st: re: generating variable with a random component

Hi,
I have a run a VAR analysis with 5 variables and have obtained both the fitted values and the residuals from each equation:
var U Y P i credit, lags(1/2) exog(L.LTV_1 L.LTV_2 L.LTV_3 L.LTV_4 timevar)
At this point I'd like to generate a set of bootstrapped variables for each of my variables that has the following format:
Y(tilda) = Y(hat) + resid(hat). However, I want the resid(hat) to be drawn at random. Is there a way to do this in Stata?
Something like "gen y_tilda = y_hat + rand(resid_hat)". I realize the "rand" part is incorrect (this is where I really need the help).
Any advice would be greatly appreciated.
Thanks,
