st: RE: Regression on rankings

["Verkuilen, Jay" <JVerkuilen@gc.cuny.edu>]

>I have a variable var1 which ranks the performance of 140 countries for
15 years. I want to examine whether another categorical variable var2
has an effect on the performance ranking using the available panel data.
Can you suggest a way?<

Rankings are tricky things. It's not remotely clear that you can compare
them over time meaningfully, at least not without making some pretty
tall assumptions about the underlying utility functions or data
generating mechanism. You may want to look at -rologit-, though.
