AW: AW: st: AW: generate lognormal RV less than 20000 observations.

Hmmm, as I said, you can pass the # of observations directly to the command,
as demonstrated earlier, so the -keep- line is not really necessary. What is
-return- supposed to do? I bet it leads to an error message...

Hi, Martin,
   I am sorry that I am really a novice for stata. Basically I have the
following code:

rndlgn 20000 0 0.5
keep in 1/500
return x1

Is it correct?
thanks

samn
