Brain fart...Calculating Gini Coefficient. Anyone decent at math?

[rmorse]

Hey guys,

I am working on econ hw, and having a brain fart. This is my formula:

I know what all my variables are. Just to double check, this means I calculate ((N+1)/(N-1) - (2/N(N-1)mu)) first, then multiply it by the sum of all PiXi, right?


Thanks!

Or do I Calculate (2/N(N-1)mu)(Sum of all that junk) And subtract that from (N+1)/(N-1)?

Its gotta be the second one. I got .4174 doing it that way....

I can do letters and words, but you start throwing in numbers and I run to the corner and start calling for my mom.
