x |
List containing: |
gini
compute point and synthetic Gini indexes on a variable y
, e.g. income, on a statistical population that could be partitioned in g
subpopultions and could be considered as sum of c
sources, e.g. income sources.
index |
String denoting computed index. |
decomposition |
array containing the decompositions. |
x |
object usually of class |
