I am sure there must be better ways. But one long tedious way could be to -generate 4 (indicator) variables for each response -by country generate total for each response corresponding to the above variables, lets say bi (i=1-4) -generate total obs var for each country bys country:gen new_var=_N -and within a forvalues loop (i=1/4) generate percentage_share=bi/new_var if response==i On Mon, Aug 9, 2010 at 2:39 PM, <rado645-bg@yahoo.de> wrote: > Dear all, > > I hope that you would help me with the following technical problem. > > > I have a dataset based on a question with four different possible answers.
