Februar 2009 14:22 An: statalist@hsphsun2.harvard.edu Betreff: Re: st: Fixing the value in egen command Dear Statalisters: Some time back, I asked in a panel data if I want to generate a variable which takes the value equal to the mean of GDP I use the command by country year, sort : egen float abxx = mean(GDP) I wanted to make another variable that contains initial value of GDP fixed (for all years) equal to e.g. value of GDP in year 1885 corresponding to each country. The solution for this modification suggested by Maarten and Blasnik worked well for the problem. Now I face a a bit different but related problem. If e.g. the value of 1885 (as in the above question) is missing for one country then it will take the initial value equal to zero for all other years. Now my problem is: I have something like 10,000 banks and I need to take their initial level of assets (the first available value and not corresponding to a fixed year). Could their be any solution? I would be really thankful for the solution.
