Hi Statalist,
I have been using the DASP package to calculate the Gini index with
weights (my data has two columns - income and number of employees
earning that income (as weights).
The Gini index results which I get from STATA are around half the Gini
index which I get when I calculate the Gini index as twice the area
between the Lorenz curve and perfect equality (45 degrees line).
When I calculate the Gini with the covariance formula I get the same
results as when I calculate the areas (Lorenz curve).
Wat am I doing wrong with the DASP package? does anyone know how the
Gini formula in section 13.1 of the DASP manual is developed?
Thank you, Kobi
