Hello to all.
Recently I needed to compute the Gini coefficient in SPSS. When I found,
that there is no possibility to get it via DESCRIPTIVES or FREQ procedure I
tried to write a macro which would compute it for me.
Unfortunately I don't have much experience in macro writing, I don't know
how to do it. I used the equation from Sen's "On Economic Inequality", where
G is expressed as a function of a weighted sum of all personal incomes with
ordinal weights (1 for the richest, 2 for the second richest etc). I didn't
know how to compute this sum in SPSS macro and than use it in further
operations.
I have also visited WWW.SPSS.COM, but such a macro was anavailable.
Is anyone of you able to give me some brief advise how to cope with the
problem
Thank you in advance
Michal Bojanowski
