      ^relsgini^ varname [^if^ exp] [^in^ range] [fweights] [^,^ ^d^elta^(^#[^,^#[^,^...]]^)^ ]


These four ado-files provide a variety of measures of inequality.  ^atkinson^
computes the Atkinson inequality index using the inequality aversion para-
meter(s) specified in the parameter list. ^inequal^ displays the following
measures: relative mean deviation, coefficient of variation, standard 
deviation of logs, Gini index, Mehran index, Piesch index, Kakwani index, 
Theil entropy index, and mean log deviation.  ^lorenz^ displays a Lorenz curve.
^relsgini^ computes the Donaldson-Weymark relative S-Gini using the
distributional sensitivity parameters specified in the parameter list.





Options
-------

^d^elta^()^ specifies the distributional sensitivity parameters used in computing
   the relative S-Gini.

^e^psilon^()^ specifies the inequality aversion parameters used in computing
    Atkinson inequality index.

^of^fset specifies the graph options "noaxis xline(0,1) yline(0,1)".
