st: RE: Negative incomes and income components using -sgini- |

. findit sgini got hits, but none that matched -sgini- exactly. In any case, it is the poster's duty to explain where user-written programs referred to come from. Nick n.j.cox@durham.ac.uk David Coyne I've been attempting to decompose the Gini coefficient of a measure C, where C=A-B. I have two questions related to this. First, if C has some values that are negative, how does this affect the interpretation of the Gini coefficient? Second, if B is nonnegative, (i.e. using -sgini- would have me use C=A + (-B), so if (-B) < 0 for all observations) thus leaving me with a negative contribution (s*g*r) to the Gini coefficient of C, does that mean that B has an equalizing effect on C? Not sure of the interpretation of this. Any insight and/or advice would be appreciated! * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
