Hi
Just would like to verify that the following works. I am mainly concerned because the gap between the last two years is three while for the others the gap is two.
Here goes:
I have data for years 1991 1993 1995 1997 and 2000. I would like to create the lags of a variable LAGVAR, this is what I have done:
ge LAGVAR1=VAR-L2.VAR
foreach i of numlist 2000 { replace LAGVAR1=. if wave==`i' }
ge LAGVARl2=LAGVAR-L3.LAGVAR
foreach i of numlist 1991 1993 1995 1997 { replace LAGVAR2=. if wave==`i' }
ge LAGVAR=LAGVAR1 if LAGVAR1~=.
replace LAGVAR=LAGVAR2 if LAGVAR2~=.
Any help is much appreciated.
Maureen
