Description Usage Arguments Value References Examples
The function computes individual components of Theil's T index (or Theil's first measure) and their group-based decompositions. It takes as input an outcome variable, a grouping variable, and an optional sampling weight. It returns a data matrix of three columns containg individual contributions and their between- and within-group components.

x |
Input continuous variable such as income. |
g |
A grouping variable containing integers, such gender coded 1 & 2. |
w |
An optional sampling weight variable. |
The function outputs three variables, g.i, g.ikb, and g.ikw.
g.i |
This variable gives the individual contribtions to the overall Gini index. |
g.ikb |
This variable provides for each individual component of the Gini its between-group subcomponent. |
g.ikw |
This variable provides for each individual component of the Gini its within-group subcomponent. The g.ikb and g.ikw sum up to g.i for each i observation. |
