st: assign a mean/median a value to a new variable

[Shuaizhang Feng <fengsz@yahoo.com>]

Dear all:

Suppose I have a data set that only contains one variable Y. and I want to add a variable x that equals the mean (or median) of Y for all observations. How do I do that?  Apparantly x=mean(Y) doesn't seem to work. 

Thank you for your help.
