Demeaning panel data

[ivov]

Hey all,

I am currently working with a panel dataset and I need to demean my variables in Eviews8. I've 12 periods and about 170 countries per variable. Is there an easy way to subtract the mean value of the variable over the 12 periods per country from each of the datapoints per country?

To illustrate, let's say that average economic growth for a country over the past 3 years was 3%. Economic growth was 4%, 2% and 3% in 2000, 2001 and 2002 for example. Then I'd like to generate a new series in which the mean over the periods is subtracted from the actual variables, so it'll become 1%, -1% and 0% respectively. In the real case, the mean should be calculated for each of the 170 countries separately and then subtracted from the datapoints of that country in 1 go. Is this possible?

Thanks a lot for your help.
