Hello, I'm new here and I hope I can get some help.
I have a database with 60 countries and I'm making a study about economic, health etc situation in different nations. This study should reveal the 'big picture' of economy, health in the world, so I made a new variable 'Regions' and I grouped the countries in 10 regions/continents. The I split the file by Regions, nut when I run any analysis, this warning appears:
"The file is not sorted in a consistent manner on the split file variables. It is likely that any procedure output will be incorrect".
My questions are:
1. Is this because the valid answers differ so much in the groups? (1000 vs. 5000), because some regions have 1 or 2 countries and others have more than 5? If that's the problem, what can I do? Should I reduce the number of countries in some regions?
2. There is an other way I can work with this database?
3. This kind of study can only be comparative, right?
