Title: rolling regression

Dear Stata Users:

Can you help me please. I want to estimate income elasticities of energy demand and record how they change by adding one observation at a time. If I understand this correctly I have to do a rolling regression. How do I program a "rolling regression" in Stata 8? I want to do a rolling regression in a loop. Each time through the loop, I want to add one period to the end of the estimation range, keeping the starting date fixed and saving estimated coefficients each time

thank you
