Dear stata users,

i do have the following problem in generating a new variable: I need
to generate a variable which takes the value of the average values of
the five preceding years of another variable that I have in my
dataset.
In other words, supposing my new variable is y at time t, I need that
its value is equal to the average of another variable (say x) from t-1
to t-5.

Since I am just beginning in using Stata anyone knows how can I deal
with this or find any help?

Thank to all of you in advance,
Regards,
Emanuele.
