I need advice on a simple program I am trying to run which does not work. I want to include an IF statement within a loop. The data is a panel series in long form, so variable year is a repeated series

SERIES INF
For !YR=1990 to 2017
If year =!yr then
GENR inf=f{!yr}cpi
endif
next

The series inf remains blank. How do i fix this?
thank you

Try

Code: Select all

smpl if year = !yr
inf=f{!yr}cpi
smpl @all

Hi
thank you but the smpl function does not work as the data is a panel. so the sample is country and time. I have a separate variable for year and country.
Is there a way around this?

Hello,

If you're saying that variable "year" is a series, then the "year = !yr" expression is not meaningful as part of an if statement conditional. Can you describe what you're trying to accomplish with your code?
