Gini index, with within- and between-group inequality decomposition
--------------------------------------------------------------------

ginidesc varname  [[fweights aweights] if exp in range]
        ,bygroup(groupvar) [mat(matname) gkmat(matname)]


This ado-file provides the Gini coefficient for the whole population,
for each subgroup specified in groupvar, and its Pyatt's (1976)
decomposition in between-, overlap- and within-group inequality.
Groupvar is a categorical variable (not string) who determines the
subgroups in which the population will be divided.
It's mandatory that the command ineqdeco (S. P. Jenkins, 1998) are
installed.

Options (Saved results)
------------------------

mat(matname)    Define a 4*2 matrix containing the inequality
                decomposition shown on the table displayed by the
                command.

gkmat(matname)  Define a K*2 matrix containing the values of the ca-
                tegorical variable in the first column, and the co-
                rresponding Gini coefficients in the second one.

你好，请问求基尼系数的命令是什么，是ginidesc Y, by(Var分组依据)吗？

请问您最后求出基尼系数分解结果了吗，最后能否求得不同群组间的地区内差距和地区间差距，贵求您的指导

请问一下能介绍一下方法吗

请问是哪篇文献介绍的啊
