The goal of GiniDecompLY is to use the approach of Lerman and Yitzhaki (1985) to decompose the Gini Index by income sources.
The package provides a set of functions that quantify the effect of each income source on inequalities.
You can install the released version of GiniDecompLY from GitHub with:
