Graphing the results of the "ginidesc" command (Gini coefficient) by year.

[Vicente Tirado]

Hi!
I estimated the Gini coefficients by year with:

 ginidesc income, by(year)

After obtaining these results I would like to plot them in the same way I did with average incomes to get something like this:



The only way I can think it could be done is by creating a constant (within varlist) containing the Gini_k just like I did with

 egen meanincome = mean(income), by(year)

and then

egen tag = tag(year)
twoway connected meanincome year if tag

but the egen command doesn't work with "ginidesc" as it does with "mean".

Also after the ginidesc results "Stored in matrix" is displayed. I thought I could access those results and somehow create the constant variable, but I didn't get anything by running

return list

Any help would be greatly appreciated!
Vicente

Please guys, I still can't find a solution.

you don't show your data (use dataex if you are going to please - see the FAQ) nor the command you used (there is no ginidesc command but I'm guessing you used ineqdeco from the ginidesc package????); please read the FAQ and then re-ask following the FAQ

my current guess is that you will need to run ineqdeco (if that is the command you are using) for each year and save the returned result you want (presumably "r(gini)") and then do your graph

GINIDESC, at least the version I have from SCC, does not return its results.
An alternative is to install EGEN_INEQUAL from SSC and try this

use http://www.stata-press.com/data/r9/nlswork , clear
gen w = exp(ln_wage)
egen gini = inequal(w) , by(year) index(gini)
scatter gini year ,connect(l) sort
