creating dummies

[manps20]

I am currently very new to eviews and was wondering how to generate dummies for time series regression. I have GDP as my dependent variable and gov't spending, exports, imports, investment etc.... as my independent variables. I need to generate dummies for every independent variable in order to compare the results from two different time periods. E.g. from year 2000 - 2003 I need one set of dummies and for 2004 - 2010 I need the next set of dummies. I am currently using eviews 6 student edition.

Code: Select all

series dummy = @recode(@year>=2000 and @year<=2003,1,0)

or

Code: Select all

series dummy = 0 smpl if @year>=2000 and @year<=2003 series dummy = 1 smpl @all
